Chromatic Number and some Properties of Pseudo-Von Neumann Regular graph of Cartesian Product of Rings

open access: yesTikrit Journal of Pure Science, 2020
Let R be a commutative ring, the Pseudo – Von Neumann  regular graph of the ring R is define as a graph whose vertex set consists of all elements of R and any two distinct vertices a and b are adjacent if and only if , this graph is denoted by P-VG(R ...

Groups with many roots [PDF]

open access: yesInternational Journal of Group Theory, 2020
Given a prime $p$‎, ‎a finite group $G$ and a non-identity element $g$‎, ‎what is the largest number of $\pth$ roots $g$ can have? We write $\myro_p(G)$‎, ‎or just $\myro_p$‎, ‎for the maximum value of $\frac{1}{|G|}|\{x \in G‎: ‎x^p=g\}|$‎, ‎where $g ...

On the continuous dependence of the solution of a boundary value problem on boundary conditions. Elements of p-regularity theory

open access: yesДоклады Академии наук, 2019
The problem of the existence of a continuous dependence of the solution of a boundary value problem on a parameter is considered. In this paper, it is proved that, in the presence of the p-regularity property, there exists a solution that continuously depends on a small parameter. The main result of the paper is based on theorems representing different

p-th Order Optimality Conditions for Singular Lagrange Problem in Calculus of Variations. Elements of p-Regularity Theory [PDF]

open access: yes, 2013
This paper is devoted to singular calculus of variations problems with constraints which are not regular mappings at the solution point, e.i. its derivatives are not surjective. We pursue an approach based on the constructions of the p-regularity theory.
