Regularity results for degenerate elliptic equations related to Gauss measure
, 2007 In this paper we study a Dirichlet problem relative to the equation Lu = gφ− (f iφ)xi , where L is a linear elliptic operator with lower-order terms whose ellipticity condition is given in terms of the function φ(x) = (2π)− 2 exp ( − |x| /2 ) , the ...

A CERTAIN EXAMPLE FOR A DE GIORGI CONJECTURE
, 2014 . In this paper, we illustrate a counter example for theconverse of a certain conjecture proposed by De Giorgi. De Giorgisuggested a series of conjectures, in which a certain integral condi-tion for singularity or degeneracy of an elliptic operator is ...

Spatial boundary problem with the Dirichlet-Neumann condition for a singular elliptic equation
, 2012 The present work devoted to the finding explicit solution of a boundary problem with the Dirichlet-Neumann condition for elliptic equation with singular coefficients in a quarter of ball. For this aim the method of Green's function have been used. Since,

Double phase anisotropic variational problems involving critical growth
Advances in Nonlinear AnalysisIn this study, we investigate some existence results for double phase anisotropic variational problems involving critical growth. We first establish a Lions-type concentration-compactness principle and its variant at infinity for the solution space ...
