Consider the equation div$(\varphi^2 \nabla \sigma)=0$ in $\mathbb{R}^N,$ where $\varphi>0$. It is well-known that if there exists $C>0$ such $\int_{B_R}(\varphi \sigma)^2 dx\leq CR^2$ for every $R\geq 1$ then $\sigma$ necessarily constant. In this paper we prove result not true replace $R^2$ by $R^k$ $k>2$ any dimension $N$. This question related to a conjecture De Giorgi.
Let $\Omega$ be a subdomain of $\mathbb{C}$ and let $\mu$ positive Borel measure on $\Omega$. In this paper, we study the asymptotic behavior eigenvalues compact Toeplitz operators $T\_\mu$ acting Bergman spaces $(\lambda n(T\mu))$ decreasing sequence $T\_\mu$, $\rho$ an increasing function such that $\rho (n)/n^A$ is for some $A>0$. We give explicit necessary sufficient geometric condition in ...
تعریف کاراتئودوری از مشتق چنین است:میگوییم تابع $f$ در نقطه $ain D_f$ مشتقپذیر است هرگاه یک تابع $varphi$ وجود داشته باشد که در $a$ پیوسته باشد و برای هر $x$ در یک بازه باز $U$ شامل $a$،[f(x)-f(a)=varphi(x)(x-a).]در این مقاله به بررسی این تعریف از مشتق می پردازیم. نشان می دهیم که با تعریف استاندارد (کوشی) از مشتق معادل است و می تواند در اثبات ساده تری از بعضی قضایای مقدماتی...
A module $$M$$ is said to be distributive (resp., uniserial) if the submodule lattice of a chain) Any uniserial but ring integers non-uniserial as $$\mathbb{Z}$$ -module. Direct sums (resp. modules are called semidistributive serial) modules. If $$A$$ with automorphism $$\varphi$$ , then we denote by $$A((x,\varphi))$$ skew Laurent series coefficient in which addition naturally defined and mult...
We prove that under some mild conditions on the symbol $$\varphi ,$$ spectrum of corresponding composition operator $$C_\varphi $$ Korenblum type spaces $$A_{-}^{-\alpha }$$ and $$A_{+}^{-\alpha contains a closed ball positive radius.
This paper is devoted to the smooth and stationary Wong-Zakai approximations for a class of rough differential equations driven by geometric fractional Brownian path $\boldsymbol{\omega}$ with Hurst index $H\in(\frac{1}{3},\frac{1}{2}]$. We first construct approximation $\boldsymbol{\omega}_{\delta}$ probabilistic arguments, then using theory obtain solution on any finite interval. Finally, bot...
In this paper we state the following weighted Hardy type inequality for any functions $ \varphi in a Sobolev space and weight \mu of quite general \begin{document}$ \begin{align*} c_{N, \mu} \int_{ \mathbb{R}^N}V\, \varphi^2\mu(x)dx\le \mathbb{R}^N}|\nabla \varphi|^2\mu(x)dx +C_\mu \mathbb{R}^N}W \varphi^2\mu(x)dx, \end{align*} $\end{document} where V is multipolar potential W bounded function ...
Abstract Given a hereditary property of graphs $\mathcal{H}$ and $p\in [0,1]$ , the edit distance function $\textrm{ed}_{\mathcal{H}}(p)$ is asymptotically maximum proportion edge additions plus deletions applied to graph density p sufficient ensure that resulting satisfies . The directly related other well-studied quantities such as speed for -chromatic number random graph. Let be forbidding a...
In this article, by using Moser's twist theorem, we prove that all solutions of the equation $x'' + ax^{+} - bx^{-} \varphi(x) = p(t)$ are bounded in critical situation, where $p$ is a smooth periodic function, and $\varphi$ one.
the purpose of this paper is to introduce a new mapping for a finite family of accretive operators and introduce an iterative algorithm for finding a common zero of a finite family of accretive operators in a real reflexive strictly convex banach space which has a uniformly g^ateaux differentiable norm and admits the duality mapping $j_{varphi}$, where $varphi$ is a gauge function ...
