On differential operators and differential equations on torus

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
Summary: In this paper, we consider periodic boundary value problems for a differential equation whose coefficients are trigonometric polynomials. The spaces of generalized functions are constructed, in which the problems considered have solutions, in particular, the solvability space of a periodic analogue of the Mizohata equation is constructed.

Encoding and recovery of operator values

open access: yes, 1992
We formulate the problem of recovery values of the operator y = Ax with the help of discrete information which is taken from the element x. Concrete situations are considered where A is the mth differentiation operator or the convolution operator, and ...

Saigo Fractional q-Differentiation Operator Involving Generalized q-Mittag–Leffler Function

open access: yesJournal of Mathematics
The purpose of this study is to obtain the images of the generalized q-analogue of Mittag–Leffler functions under the Saigo fractional q-differentiation operator, where its argument consists of a factor xζxq−μ+ξ−θ.

Supercyclic properties of extended eigenoperators of the differentiation operator on the space of entire functions [PDF]

open access: yes
A continuous linear operator L defined on the space of entire functions H(C) is said to be an extended λ-eigenoperator of the differentiation operator D provided DL = λLD.

Parabolic equation with exponential nonlinearity as the condition of joint venture linear system

open access: yesНаука. Инновации. Технологии, 2022
An attempt is made to construct a 2 + 1 - dimensional nonlinear model that is a condition for the compatibility of a system of two first - order linear differential equations. The resulting equation is related to the operator L, A to the pair and the Lax

State Entropy and Differentiation Phenomenon

open access: yesEntropy, 2018
In the formalism of quantum theory, a state of a system is represented by a density operator. Mathematically, a density operator can be decomposed into a weighted sum of (projection) operators representing an ensemble of pure states (a state distribution)

On the $n$-similarity of the operators which are left inverse to the $n^{th}$ degree of the integration operator in the spaces of analytic functions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2012
We investigate the conditions of the $n$-similarity of the $n^{m th}$ degreeof the differentiation operator to an operatorwhich is left inverse to the $n^{m th}$ degree of the integration operator in the spaces ofanalytic functions.

Solvability of fractional analogues of the Neumann problem for a nonhomogeneous biharmonic equation

open access: yesElectronic Journal of Differential Equations, 2015
In this article we study the solvability of some boundary value problems for inhomogenous biharmobic equations. As a boundary operator we consider the differentiation operator of fractional order in the Miller-Ross sense.
