SURJECTIVITY OF CONVOLUTION OPERATORS [PDF]

open access: yes, 2023
In this article, we will explain the surjectivity of convolution operators on Euclidean spaces and on noncompact symmetric spaces. We will also give an application of our main result to PDE theory.

Surjective polymorphisms of reflexive cycles

open access: yesCoRR, 2022
A reflexive cycle is any reflexive digraph whose underlying undirected graph is a cycle. Call a relational structure Slupecki if its surjective polymorphisms are all essentially unary. We prove that all reflexive cycles of girth at least 4 have this property.

Some surjectivity theorems with applications [PDF]

open access: yes, 2013
summary:In this paper a new class of mappings, known as locally $\lambda $-strongly $\phi $-accretive mappings, where $\lambda $ and $\phi $ have special meanings, is introduced.

Criterion for surjectivity of localization in Galois cohomology of a reductive group over a number field

open access: yesComptes Rendus. Mathématique, 2023
Let $G$ be a connected reductive group over a number field $F$, and let $S$ be a set (finite or infinite) of places of $F$. We give a necessary and sufficient condition for the surjectivity of the localization map from $H^1(F,G)$ to the “direct sum” of ...

Arithmetic surjectivity for zero-cycles [PDF]

open access: yesMathematical Research Letters, 2020
Let $f:X\to Y$ be a proper, dominant morphism of smooth varieties over a number field $k$. When is it true that for almost all places $v$ of $k$, the fibre $X_P$ over any point $P\in Y(k_v)$ contains a zero-cycle of degree $1$? We develop a necessary and sufficient condition to answer this question.

The Dunkl convolution operators and multipoint de la Vallee–Poussin problem

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
The Dunkl operator as an object of mathematical physics is considered, we study the kernel and the surjectivity of Dunkl convolution operators in the space of entire functions and the space of entire functions of exponential type.

Existence and Uniqueness of Solutions for the p(x)-Laplacian Equation with Convection Term

open access: yesMathematics, 2020
In this paper, we consider the existence and uniqueness of solutions for a quasilinear elliptic equation with a variable exponent and a reaction term depending on the gradient.
