On uniqueness of entropy solutions for nonlinear elliptic degenerate anisotropic equations
Journal Title: Математичні Студії - Year 2017, Vol 47, Issue 1
Abstract
In the present paper we deal with the Dirichlet problem for a class of degenerate anisotropic elliptic second-order equations with L1-right-hand sides in a bounded domain of Rn (n⩾2). This class is described by the presence of a set of exponents q1,…,qn and a set of weighted functions ν1,…,νn in growth and coercitivity conditions on coefficients of the equations. The exponents qi characterize the rates of growth of the coefficients with respect to the corresponding derivatives of unknown function, and the functions νi characterize degeneration or singularity of the coefficients with respect to independent variables. Our aim is to study the uniqueness of entropy solution of the problem under consideration.

Rings with the Kazimirsky condition and rings with projective socle
We construct the theory of diagonalizability for matrices over Bezout rings of stable range 1 with the Kazimirsky condition. It is shown that a ring of stable range 1 with the right (left) Kazimirsky condition is an elem...
Subnormal independent random variables and Levy’s phenomenon for entire functions
Suppose that (Zn) is a sequence of real independent subnormal random variables, i.e. such that there exists D>0 satisfying following inequality for expectation E(eλ0Zk)≤eDλ20 for any k∈N for all λ0∈R. In this paper is pr...

This review is an extended version of my short review of Urbanek's book that was published in MathSciNet. Here it is written about his book in greater detail, which was not possible in the short review. I will present fa...
Growth of p-th means of the Poisson-Stieltjes integrals in polydisc
We prove a sharp upper estimate of the pth means of the Poisson-Stieltjes integrals in the unit polydisc for p>1. The estimate is given in terms of the smoothness of a complex-valued Stieltjes measure μ. If the measure μ...
Fast growing meromorphic solutions of the systems of linear differential equations
Systems of linear differential equations that allow for dimension decrease are considered. Growth estimates for meromorphic vector-solutions are obtained. An essentially new feature is that there are no additional constr...
