Viscoacoustic anisotropic wave equations [PDF]

SEG Technical Program Expanded Abstracts 2019, 2019
The wave equation plays a central role in seismic modeling, processing, imaging and inversion. Incorporating attenuation anisotropy into the acoustic anisotropic wave equations provides a choice for acoustic forward and inverse modeling in attenuating anisotropic media.

On the solutions of the anisotropic Heisenberg equation

Journal of Physics A: Mathematical and General, 1994
Summary: A method based on the discrete group of the inner symmetry of integrable systems is used to derive explicit formulae for soliton-like solutions of Heisenberg ferromagnets (with biaxial or uniaxial anisotropy). The solutions are given in terms of expressions which involve ratios of two determinants.

Nonlinear anisotropic parabolic equations in Lm

Arab Journal of Mathematical Sciences, 2014
In this paper, we give a result of regularity of weak solutions for a class of nonlinear anisotropic parabolic equations with lower-order term when the right-hand side is an Lm function, with m being ”small”.

Local Regularity Results for Minima of Anisotropic Functionals and Solutions of Anisotropic Equations

Journal of Inequalities and Applications, 2008
This paper gives some local regularity results for minima of anisotropic functionals I(u;Ω)=∫Ωf(x,u,Du)dx, u∈Wloc1,qi(Ω) and for solutions of anisotropic equations −div𝒜(x,u,Du)=-∑i=1N(∂f/∂

On some nonlinear anisotropic elliptic equations in anisotropic Orlicz space [PDF]

Arab Journal of Mathematical Sciences, 2023
Purpose – In the present paper, the authors will discuss the solvability of a class of nonlinear anisotropic elliptic problems (P), with the presence of a lower-order term and a non-polynomial growth which does not satisfy any sign condition which is ...

Capillary Schwarz symmetrization in the half-space

Advanced Nonlinear Studies, 2023
In this article, we introduce a notion of capillary Schwarz symmetrization in the half-space. It can be viewed as the counterpart of the classical Schwarz symmetrization in the framework of capillary problem in the half-space.

Regularity results for local solutions to some anisotropic elliptic equations [PDF]

Israel Journal of Mathematics, 2020
In this paper we study the higher integrability of local solutions for a class of anisotropic equations with lower order terms whose growth coefficients lay in Marcinkiewicz spaces. A condition for the boundedness of such solutions is also given.

On a class of singular anisotropic (p, q)-equations [PDF]

Revista Matemática Complutense, 2021
AbstractWe consider a Dirichlet problem driven by the anisotropic (p, q)-Laplacian and with a reaction that has the competing effects of a singular term and of a parametric superlinear perturbation. Based on variational tools along with truncation and comparison techniques, we prove a bifurcation-type result describing the changes in the set of ...

Exact Solutions of Reaction–Diffusion PDEs with Anisotropic Time Delay

Mathematics, 2023
This study is devoted to reaction–diffusion equations with spatially anisotropic time delay. Reaction–diffusion PDEs with either constant or variable transfer coefficients are considered.
