Entropy dissipation estimates for the linear Boltzmann operator [PDF]

, 2015
We prove a linear inequality between the entropy and entropy dissipation functionals for the linear Boltzmann operator (with a Maxwellian equilibrium background).

L0-Linear Modulus of a Random Linear Operator

Abstract and Applied Analysis, 2014
We prove that there exists a unique L0-linear modulus for an a.s. bounded random linear operator on a specifical random normed module, which generalizes the classical case.

Topological methods on solvability, multiplicity and bifurcation of a nonlinear fractional boundary value problem

Electronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we first prove new properties of the $(a, q)$-stably solvable maps for a class of decomposable operators in the form of $LF$, where $L$ is a bounded linear operator and $F$ is nonlinear.

Estimates of approximative characteristics of the classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables with given majorant of mixed moduli of continuity in the space $L_{q}$

Karpatsʹkì Matematičnì Publìkacìï, 2019
In this paper, we continue the study of approximative characteristics of the classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables whose majorant of the mixed moduli of continuity contains both exponential and logarithmic multipliers.

Solving the difference initial-boundary value problems by the operator exponential method [PDF]

, 2000
We suggest a modification of the operator exponential method for the numerical solving the difference linear initial boundary value problems. The scheme is based on the representation of the difference operator for given boundary conditions as the ...

Inclusion Properties on a Class of Meromorphic Functions Defined by a Linear Operator

Journal of Mathematical and Fundamental Sciences, 2016
In the present paper, we study a certain class of meromorphic univalent functions f(z) dened by the linear operator L(α,β) f (z). The aim of the present paper is to prove some properties for the class Σα,β,kλ;(h) to satisfy the certain subordination ...

Linear Operators That Preserve Two Genera of a Graph

Mathematics, 2020
If a graph can be embedded in a smooth orientable surface of genus g without edge crossings and can not be embedded on one of genus g − 1 without edge crossings, then we say that the graph has genus g.
