Green’s function and positive solutions for a second-order singular boundary value problem with integral boundary conditions and a delayed argument. (English) Zbl 07022300
Summary: This paper investigates the expression and properties of Green’s function for a second-order singular boundary value problem with integral boundary conditions and delayed argument $$- x^{\prime \prime} \left(t\right) - a \left(t\right) x' \left(t\right) + b \left(t\right) x \left(t\right) = \omega \left(t\right) f \left(t, x \left(\alpha \left(t\right)\right)\right), t \in \left(0, 1\right); x' \left(0\right) = 0, x \left(1\right) - \int_0^1 h \left(t\right) x \left(t\right) d t = 0$$, where $$a \in \left(\left[0, 1\right], \left[0, + \infty\right)\right), b \in C \left(\left[0, 1\right], \left(0, + \infty\right)\right)$$ and, $$\omega$$ may be singular at $$t = 0$$ or/and at $$t = 1$$. Furthermore, several new and more general results are obtained for the existence of positive solutions for the above problem by using Krasnosel’skii’s fixed point theorem. We discuss our problems with a delayed argument, which may concern optimization issues of some technical problems. Moreover, the approach to express the integral equation of the above problem is different from earlier approaches. Our results cover a second-order boundary value problem without deviating arguments and are compared with some recent results.

## Resolution of Russell's and Cantor's paradoxes

 Quote by micromass Ah, but the same conclusion holds. Let p="Dan is completely legless and his right ankle is bleeding", then p is false. Thus the implication $p\rightarrow q$ holds true never the less. Why is p false? Well, p is the conjuction p= "Dan is completely legless" AND "His right ankle is bleeding". And this conjunction is clearly false.
Dear Micromass,

If we can derive anything from a contradiction will the thing we derive this way be of any value for us? Will this thing be logically grounded if this could be anything?

For example, we can derive "he should be taken to the nearest hospital for legless people And he should not be taken to the nearest hospital for legless people" from any contradiction (including the above- "Dan is completely legless" AND "His right ankle is bleeding"). Right?

Yours,

Dan

Yes, it will be logically grounded. The truth table of the implication is logically sound. There are no problems with this.

 For example, we can derive "he should be taken to the nearest hospital for legless people And he should not be taken to the nearest hospital for legless people" from any contradiction (including the above- "Dan is completely legless" AND "His right ankle is bleeding"). Right?
Yes, from a false hypothesis, we can derive everything. In latin: "ex falso sequitur quodlibet". This is not a flaw in logic, however it might be confusing to some. For example, the following is also true

"Dan is completely legless and his right ankle is bleeding" THEN "1+1=3"

This does not make 1+1=3 true. It only makes the implication true.

Dear Micromass,

I completely agree that the implication is true. My point is if we get something this way can this something (not the implication but what we get from it) be considered to be logically grounded?

Yours,

Dan

Well, everything we get from following logical inference rules will be logically valid. So yes.

Dear Micromass,

Do you mean if we get "1+1=3" from some contradiction, "1+1=3" by itself is logically grounded?

As far as I understand if something can be derived only from some contradiction it is not logically valid at all.

Yours,

Dan

Yes, provided that the contradiction is logically grounded.

 Quote by micromass Yes, provided that the contradiction is logically grounded.
Dear Micromass,

If contradiction is just given to you, like, say, the following way:
If (this forum exists and it does not exist) Then 1+1=3, will you consider "1+1=3" logically grounded?

Yours,

Dan

No, since the premise is false.

 Dear Micromass, That is my point! If we analyze the formula: R = {x: x∉x} ⇒ R ∈ R ↔ R ∉ R we can see that it is actually the following one: (R = {x: x∉x} And R ≠ {x: x∉x}) ⇒ R ∈ R ↔ R ∉ R. That, in my opinion, makes "R ∈ R ↔ R ∉ R" logically ungrounded. Yours, Dan

It's not logically ungrounded, since it can be logically proven. The premise is true, thus so must the conclusion.

Sorry but how can this (R = {x: x∉x} And R ≠ {x: x∉x}) be a true premise?!

If it can be proven with inference rules then it is a true premise. And since $R\in R~\leftrightarrow R\notin R$ can be proven from the axioms and the inference rules, means that it is true.

Dear Micromass,

What I mean is "R ∈ R ↔ R ∉ R" can be derived only from (R = {x: x∉x} And R ≠ {x: x∉x}) .
Does not this alone make "R ∈ R ↔ R ∉ R" logically ungrounded?

Yours,

Why can it be derived only from that?? It can also be derived from $R=\{x~\vert~x\notin x\}$. There is no need for $(R=\{x~\vert~x\notin x\}~\text{and}~R\neq \{x~\vert~x\notin x\})$. In fact, that is still true, but there's no need for it.

Dear Micromass,

If R ∈ R R ≠ {x: x∉x}. That is so because under the assumption “R ∈ R” R includes a member that is included in itself (R itself is such a member). Do you agree?

That is, when we write
R = {x: x∉x} And R ∈ R -> R ∉ R
it is equivalent to
R = {x: x∉x} And R ≠ {x: x∉x} And R ∈ R -> R ∉ R which is equivalent to
R = {x: x∉x} And R ≠ {x: x∉x} ⇒ R ∈ R -> R ∉ R

Yours,

Dan

Yes, I agree that $R\in R~\rightarrow~R\notin R$ can be derived from that. But why can it only be derived from that?

 Quote by micromass Yes, I agree that $R\in R~\rightarrow~R\notin R$ can be derived from that. But why can it only be derived from that?
Dear Micromass,

That is so because:
1. The only way to derive R ∉ R is (R = {x: x∉x} And R ∈ R). Right?
2. (R = {x: x∉x} And R ∈ R) is equivalent to (R = {x: x∉x} And R ≠ {x: x∉x} And R ∈ R). Right?
3. From 1. and 2. you can see that when you derive R ∉ R from (R = {x: x∉x} And R ∈ R) you actually derive R ∉ R from (R = {x: x∉x} And R ≠ {x: x∉x} And R ∈ R). You can not avoid it.

Like if you know that 2+2 = 4 you know that every time you use "2+2" you actually use "4". You can not avoid it either.

Yours,

Dan

For the class of zero diversity theories de ned earlier directional resolution will not generate any new clauses. Sometime, however, directional resolution generate clauses which are tautologies, or which are all subsumed in the original set of clauses. 14 Example 5: The odd-parity relation over n propositional symbols P1 ; :::; Pn allows all models with an odd number of \true" assignments.

# Curve is geodesic iff $\nabla_k g(V,V)$ vanishes

Let $$V$$ be a Killing vector field and let $$s \longmapsto x^i(s)$$ be a curve such that

$$\dot{x} \enspace \equiv \enspace \frac{dx^i}{dx}(s) \enspace = \enspace V^i\big(x(s)\big)$$

Show that $$x^i(s)$$ are geodesics iff

$$\nabla_k \, g(V,V) \enspace = \enspace 0$$

along the curve $$x(s)$$.

I approached it as follows:

$$x^i(s)$$ is geodesic if it satisfies the geodesic equation, i.e.

$$\ddot{x}^i + \Gamma^i_{jk} \,\dot{x}^j \, \dot{x}^k \enspace = \enspace 0$$

I calculated

\begin{align} \ddot{x}^i + \Gamma^i_{jk} \, \dot{x}^j \, \dot{x}^k \enspace &= \enspace 0 \\ {} \\ &= \enspace \tfrac{d}{ds} \dot{x}^i + \Gamma^i_{jk} \, \dot{x}^j \, \dot{x}^k \\ {} \\ &= \enspace \tfrac{d}{ds} V^i\big(x(s)\big) + \Gamma^i_{jk} \, \dot{x}^j \, \dot{x}^k \\ {} \\ &= \enspace \frac{\partial V^i}{\partial x^k} \, \frac{dx^k}{ds} + \Gamma^i_{jk} \, \dot{x}^j \, \dot{x}^k \\ {} \\ &= \enspace \partial_k V^i \, \dot{x}^k + \Gamma^i_{jk} \, \dot{x}^j \, \dot{x}^k \\ {} \\ &= \enspace \Big( \nabla_k V^i \Big) \, \dot{x}^k \\ {} \\ &= \enspace V^k \, \nabla_k V^i \tag{1}\\ {} \\ &= \enspace 0 \end{align}

However, the term $$\nabla_k \, g(V,V)$$ should yield

$$\nabla_k \, g(V,V) \enspace = \enspace 2 \cdot g_{ij} V^j \, \nabla_k V^i \enspace = \enspace 2 \cdot V_i \, \nabla_k V^i \enspace = \enspace 0$$

$$\Longrightarrow \quad V_i \, \nabla_k V^i \enspace = \enspace 0 \tag{2}$$

What went wrong in this calculation? How does the discrepancy arise? Is the approach just flawed or is there an additional step that somehow converts equation (1) into equation (2) and vice versa?

Since $$V$$ is a Killing vector field, $$\nabla_iV_j=-\nabla_jV_i$$. Using this in equation 2, the desired relation follows.
• Argh surely! The one condition for $V$ that is explicitly required to hold and I did not think of it. I am an idiot. ^^ Thank you so much for your answer! Mar 24, 2021 at 18:29

### LabelUp(axis)

Draw numerical Plot labels upright?

#### Description:

This attribute controls the appearance of an annotated coordinate grid (drawn with the astGrid function) by determining whether the numerical labels for each axis of a Plot should be drawn upright or not. It takes a separate value for each physical axis of a Plot so that, for instance, the setting " LabelUp(2)=1" specifies that numerical labels for the second axis should be drawn upright.

If the LabelUp value of a Plot axis is non-zero, it causes numerical labels for that axis to be plotted upright (i.e. as normal, horizontal text), otherwise labels are drawn parallel to the axis to which they apply.

The default is to produce upright labels if the labels are placed around the edge of the plot, and to produce labels that follow the axes if the labels are placed within the interior of the plot (see attribute Labelling).

Type:
Integer (boolean).

#### Applicability

##### Plot
All Plots have this attribute.

#### Notes:

• In some circumstances, numerical labels and tick marks are drawn around the edges of the plotting area (see the Labelling attribute). In this case, the value of the LabelUp attribute is ignored.

• If no axis is specified, (e.g. " LabelUp" instead of " LabelUp(2)" ), then a " set" or " clear" operation will affect the attribute value of all the Plot axes, while a " get" or " test" operation will use just the LabelUp(1) value.

## An Efficient Pairing-Based Shuffle Argument

File: [.pdf (713 KB)] pdf recommended.

Abstract:

We construct the most efficient known pairing-based NIZK shuffle argument. It consists of three subarguments that were carefully chosen to obtain optimal efficiency of the shuffle argument: 1 A same-message argument based on the linear subspace QANIZK argument of Kiltz and Wee, 2 A (simplified) permutation matrix argument of Fauzi, Lipmaa, and Zaj\k{a}c, 3 A (simplified) consistency argument of Groth and Lu. We prove the knowledge-soundness of the first two subarguments in the generic bilinear group model, and the culpable soundness of the third subargument under a KerMDH assumption. This proves the soundness of the shuffle argument. We also discuss our partially optimized implementation that allows one to prove a shuffle of $100\,000$ ciphertexts in less than a minute and verify it in less than $1.5$ minutes.

Cauchy problem for $\{\vec p;\vec h\}$-parabolic equations with time-dependent coefficients

V. A. Litovchenko

Chernivtsi National University named after Yuriy Fedkovych

Abstract: We establish the existence of a unique solution continuously depending on the initial data to the Cauchy problem for $\{\vec p;\vec h\}$-parabolic equations with time-dependent coefficients for which the initial data are generalized functions (distributions) of slow growth. For a particular class of equations, we state necessary and sufficient conditions for the existence of a unique solution of the Cauchy problem with properties of its spatial variable which are characteristic of its fundamental solution.

# conofinf

Cone of influence

## Syntax

```cone = conofinf(wname,scales,LenSig,SigVal)[cone,PL,PR] = conofinf(wname,scales,LenSig,SigVal)[cone,PL,PR,PLmin,PRmax] = conofinf(wname,scales,LenSig,SigVal)[PLmin,PRmax] = conofinf(wname,scales,LenSig)[...] = conofinf(...,'plot') ```

## Description

`cone = conofinf(wname,scales,LenSig,SigVal)` returns the cone of influence (COI) for the wavelet `wname` at the scales in `scales` and positions in `SigVal`. `LenSig` is the length of the input signal. If `SigVal` is a scalar, `cone` is a matrix with row dimension `length(scales)` and column dimension `LenSig`. If `SigVal` is a vector, `cone` is cell array of matrices.

```[cone,PL,PR] = conofinf(wname,scales,LenSig,SigVal)``` returns the left and right boundaries of the cone of influence at scale 1 for the points in `SigVal`. `PL` and `PR` are `length(SigVal)`-by-2 matrices. The left boundaries are`(1-PL(:,2))./PL(:,1)` and the right boundaries are`(1-PR(:,2))./PR(:,1)`.

```[cone,PL,PR,PLmin,PRmax] = conofinf(wname,scales,LenSig,SigVal)``` returns the equations of the lines that define the minimal left and maximal right boundaries of the cone of influence. `PLmin` and `PRmax` are 1-by-2 row vectors where `PLmin(1)` and `PRmax(1)` are the slopes of the lines. `PLmin(2)` and `PRmax(2)` are the points where the lines intercept the scale axis.

```[PLmin,PRmax] = conofinf(wname,scales,LenSig)``` returns the slope and intercept terms for the first-degree polynomials defining the minimal left and maximal right vertices of the cone of influence.

`[...] = conofinf(...,'plot') ` plots the cone of influence.

## Input Arguments

 `wname` `wname` is a character vector corresponding to a valid wavelet. To verify that `wname` is a valid wavelet, `wavemngr('fields',wname)` must return a struct array with a `type` field of 1 or 2, or a nonempty `bound` field. `scales` `scales` is a vector of scales over which to compute the cone of influence. Larger scales correspond to stretched versions of the wavelet and larger boundary values for the cone of influence. `LenSig` `LenSig` is the signal length and must exceed the maximum of `SigVal`. `SigVal` `SigVal` is a vector of signal values at which to compute the cone of influence. The largest value of `SigVal` must be less than the signal length, `LenSig`.If `SigVal` is empty, `conofinf` returns the slope and intercept terms for the minimal left and maximal right vertices of the cone of influence.

## Output Arguments

 `cone` `cone` isthe cone of influence. If `SigVal` is a scalar, `cone` is a matrix. The row dimension is equal to the number of `scales` and column dimension equal to the signal length, `LenSig`. If `SigVal` is a vector, `cone` is a cell array of matrices. The elements of each row of the matrix are equal to 1 in the interval around `SigVal` corresponding to the cone of influence. `PL` `PL` is the minimum value of the cone of influence on the position (time) axis. `PR` `PR` is the maximum value of the cone of influence on the position (time) axis. `PLmin` `PLmin` is a 1-by-2 row vector containing the slope and scale axis intercept of the line defining the minimal left vertex of the cone of influence. `PLmin(1)` is the slope and `PLmin(2)` is the point where the line intercepts the scale axis. `PRmax` `PRmax` is a 1-by-2 row vector containing the slope and scale axis intercept of the line defining the maximal right vertex of the cone of influence. `PRmax(1)` is the slope and `PRmax(2)` is the point where the line intercepts the scale axis.

## Examples

Cone of influence for Mexican hat or Ricker wavelet:

```load cuspamax signal = cuspamax; wname = 'mexh'; scales = 1:64; lenSIG = length(signal); x = 500; figure; cwt(signal,scales,wname,'plot'); hold on [cone,PL,PR,Pmin,Pmax] = conofinf(wname,scales,lenSIG,x,'plot'); set(gca,'Xlim',[1 lenSIG]) ```

Left minimal and right maximal vertices for the cone of influence (Morlet wavelet):

```[PLmin,PRmax] = conofinf('morl',1:32,1024,[],'plot'); % PLmin = -0.1245*u+ 32.0000 % PRmax = 0.1250*u-96.0000```

### Cone of Influence

Let ψ(t) be an admissible wavelet. Assume that the effective support of ψ(t) is [-B,B]. Letting u denote the translation parameter and s denote the scale parameter, the dilated and translated wavelet is:

`${\psi }_{u,s}\left(t\right)=\frac{1}{\sqrt{s}}\psi \left(\frac{t-u}{s}\right)$`

andhas effective support [u-sB,u+sB]. The cone of influence (COI) is the set of all t included in the effective support of the wavelet at a given position and scale. This set is equivalent to:

`$|t-u|\le sB$`

At each scale, the COI determines the set of wavelet coefficients influenced by the value of the signal at a specified position.

# Math Help - Help finding a tangent to integral

1. ## Help finding a tangent to integral

given is F(x)= the integral from x=1 to x=2x^3 of the function (3t-4)^2 dt

I need to find the equation of the tangent line to F(x) at x=-1

so far i have:

f=600 (which is the slope of F at x=-1)

i need help finding the (x,y) coordinates

$F(x)=\int_1^{2x^3}(3t-4)^2dt$

Let $u=2x^3$

$F'(x)=\frac{du}{dx}\frac{d}{du}\int_1^u(3t-4)^2dt$

$F'(x)=6x^2[3(2x^3)-4]^2$

$F'(-1)=600$

Ok, In get the same thing there. Think of the equation of the tangent line as follows:

$y-F(-1)=600[x-(-1)]$

$y-F(-1)=600(x+1)$

So you need to find

$F(-1)=\int_1^{2(-1)^3}(3t-4)^4dt$

So that's just a basic definite integral right? So just evaluate F(-1) by using the substitution rule.

As you would have noticed the beginning of the document, it was told the explanation will be based on the program we had written earlier in this series. The program was compiled using the command

$cc sample-source.c -lm  As you have probably noticed, we are linking the program with the math library. This was done intentionally to explain the dynamic loader. Any file can be identified using the file command. Running file on the a.out executable gives us some information on the type of executable. $ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1
(SYSV), dynamically linked (uses shared libs), for
GNU/Linux 2.6.32, not stripped

The description shows that the executable compiled is a ELF (Executable and Linkable Format) type executable for a 64 bit machine and used shared libraries. To find out what are all the shared libraries that went into making the ELF executable can be found using the ldd program.

\$ ldd a.out
linux-vdso.so.1 =>  (0x00007fff1d368000)
libm.so.6 => /lib64/libm.so.6 (0x0000003cede00000)
libc.so.6 => /lib64/libc.so.6 (0x0000003cece00000)
/lib64/ld-linux-x86-64.so.2 (0x0000003ceca00000)

The output shows that our tiny executable uses the services of four different shared libraries. {The linux-vdso.so library will be explained elsewhere in this series). The libm.so is the math library that we linked in while compiling out program code. The next is the standard C library. The last library is the dynamic loader which will help during the start of the program execution to use other library functions that we are linked with. This section will describe the functions of the dynamic loader in detail.

Before we can proceed with the dynamic loader in detail, there are some background information that needs to be known about the compilation process.
