A Liouville type theorem for a class of anisotropic equations

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper we are dealing with entire solutions of a general class of anisotropic equations. Under some appropriate conditions on the data, we show that the corresponding equations cannot have non-trivial positive solutions bounded from above.

Propagation of electromagnetic waves in anisotropic magnetoelectric medium

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2019
In the article we consider porpagation and interaction of electromagnetic waves of different polarization, in anisotropic medium that is inhomogeneous along the Z axis with magnetoelectric effect of tetragonal, trigonal, and hexagonal symmetries are ...

Minimal Geometric Deformation: the inverse problem

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In this paper we show that any static and spherically symmetric anisotropic solution of the Einstein field equations can be thought as a system sourced by certain deformed isotropic system in the context of Minimal Geometric Deformation-decoupling ...

Compact anisotropic models in general relativity by gravitational decoupling

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Durgapal’s fifth isotropic solution describing spherically symmetric and static matter distribution is extended to an anisotropic scenario. To do so we employ the gravitational decoupling through the minimal geometric deformation scheme.

Wiener-Hopf solution for impenetrable wedges at skew incidence [PDF]

open access: yes, 2006
A new Wiener-Hopf approach for the solution of impenetrable wedges at skew incidence is presented. Mathematical aspects are described in a unified and consistent theory for angular region problems.

Flows of singular vector fields and applications to fluid and kinetic equations [PDF]

open access: yes, 2015
Several physical phenomena arising in fluid dynamics and kinetic equations can be modeled by nonlinear transport PDE. Such quantities are the vorticity of a fluid, or the density of a collection of particles advected by a velocity field which is highly ...
