Anisotropic tempered diffusion equations [PDF]

open access: greenNonlinear Analysis, 2020
We introduce a functional framework which is specially suited to formulate several classes of anisotropic evolution equations of tempered diffusion type. Under an amenable set of hypothesis involving a very natural potential function, these models can be shown to belong to the entropy solution framework devised by 4, 5, therefore ensuring well ...

Integrable Anisotropic Evolution Equations on a Sphere

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2005
V.V. Sokolov's modifying symmetry approach is applied to anisotropic evolution equations of the third order on the n-dimensional sphere. The main result is a complete classification of such equations.

Nonlinear anisotropic parabolic equations in Lm

open access: yesArab 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”.

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

open access: yesArab 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

open access: yesAdvanced 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.

Exact Solutions of Reaction–Diffusion PDEs with Anisotropic Time Delay

open access: yesMathematics, 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.

Viscoacoustic anisotropic wave equations [PDF]

open access: yesSEG 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 a free boundary value problem for the anisotropic N-Laplace operator on an N−dimensional ring domain

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this paper we are going to investigate a free boundary value problem for the anisotropic N-Laplace operator on a ring domain Ω:=Ω0\Ω¯1⊂𝕉N\Omega : = {\Omega _0}\backslash {\bar \Omega _1} \subset {\mathbb{R}^N}, N ≥ 2.

Anisotropic parabolic equations with variable nonlinearity [PDF]

open access: yesPublicacions Matemàtiques, 2009
We study the Dirichlet problem for a class of nonlinear parabolic equations with nonstandard anisotropic growth conditions. Equations of this class generalize the evolutional p(x, t)-Laplacian. We prove theorems of existence and uniqueness of weak solutions in suitable Orlicz-Sobolev spaces, derive global and local in time L∞ bounds for the weak ...
