In this paper we prove a new version of Kransoselskii's fixed-point theorem under ($\psi, \theta, \varphi$)-weak contraction condition. The theoretical result is applied to the existence solution following fractional hybrid differential equation involving Riemann-Liouville and integral operators orders $0<\alpha<1$ $\beta>0:$ \begin{equation}\nonumber \left\{\begin{array}{ll} D^{\alpha}[x(t)-f(...

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...

muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...

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.

A way to measure the lower growth rate of φ : Ω × [ 0 , ∞ ) → $$ \varphi :\Omega \times \left[0,\infty \right)\to \right) is require t ↦ ( x − r t\mapsto \left(x,t\right){t}^{-r} be increasing in \left(0,\infty . If this condition holds with = 1 r=1 then inf u ∈ f + W ∫ | ∇ d \underset{u\in f+{W}_0^{1,\varphi}\left(\Omega \right)}{\operatorname{inf}}{\int}_{\Omega}\varphi \left(x,|\nabla u|\rig...
