Integrable Anisotropic Evolution Equations on a Sphere [PDF]

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.

On the secular equation for anisotropic wave motions [PDF]

open access: bronzeQuarterly of Applied Mathematics, 1973
In a previous paper [7] it was shown that for waves propagating in certain linear anisotropic mechanical systems there exist universal connections between the phase speeds of harmonic plane waves. Here the results are shown to hold in a wider context.

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”.

Local Regularity Results for Minima of Anisotropic Functionals and Solutions of Anisotropic Equations [PDF]

open access: goldJournal 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/∂

Anisotropic tempered diffusion equations [PDF]

open access: yesNonlinear 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 ...

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.
