Averaging anisotropic cosmologies [PDF]

, 2006
We examine the effects of spatial inhomogeneities on irrotational anisotropic cosmologies by looking at the average properties of anisotropic pressure-free models.

SURFACE EFFECT DUE TO INCIDENT PLANE SURFACE HORIZONTAL WAVES

International Islamic University Malaysia Engineering Journal, 2012
Surface effect due to incident plane surface horizontal waves through anisotropic elastic materials is studied. Mathematical formulation over the modeled earth's alluvial valley is transformed into integral equations.

Numerical Formulation of Anisotropic Elastoplastic Behavior Coupled with Damage Model in Forming Processes

Mathematics, 2022
The present paper proposes a mathematical development of the plasticity and damage approaches to simulate sheet metal forming processes. It focuses on the numerical prediction of the deformation of the sheet metal during the deep drawing process when a ...

Local regularity for an anisotropic elliptic equation [PDF]

Calculus of Variations and Partial Differential Equations, 2020
AbstractWe establish the interior Hölder continuity for locally bounded solutions, and the Harnack inequality for non-negative continuous solutions to a class of anisotropic elliptic equations with bounded and measurable coefficients, whose prototype equation is $$\begin{aligned} u_{xx}+\varDelta _{q,y} u=0\quad {\text { locally in }}{\mathbb {R ...

Global Solution for the Generalized Anisotropic Navier–Stokes Equations with Large Data

Mathematical Modelling and Analysis, 2015
We are concerned with 3D incompressible generalized anisotropic Navier– Stokes equations with hyperdissipative term in horizontal variables. We prove that there exists a unique global solution for it with large initial data in anisotropic Besov space.

Anisotropic Mesh Adaptation for Finite Element Solution of Anisotropic Porous Medium Equation [PDF]

, 2017
Anisotropic Porous Medium Equation (APME) is developed as an extension of the Porous Medium Equation (PME) for anisotropic porous media. A special analytical solution is derived for APME for time-independent diffusion. Anisotropic mesh adaptation for linear finite element solution of APME is discussed and numerical results for two dimensional examples ...

Existence and regularity results for anisotropic parabolic equations with degenerate coercivity [PDF]

arXiv, 2023
This paper deals with a class of nonlinear anisotropic parabolic equations with degenerate coercivity. Using the anisotropic Gagliardo-Nirenberg-type inequality, we prove some existence and regularity results for the solutions under the framework of anisotropic Sobolev spaces, which generalize the previous results of [10,18,23].

Magnetized Strange Quark Models in Lyra Theory

Journal of New Theory, 2023
In this study, the behavior of magnetized strange quark matter (MSQM) distribution in Lyra theory was investigated for homogeneous anisotropic Bianchi III, locally rotationally symmetric (LRS) Bianchi I, and Kantowski-Sachs universe models.

Gravitational Collapse of Phantom Fluid in (2+1)-Dimensions

, 2010
This investigation is devoted to the solutions of Einstein's field equations for a circularly symmetric anisotropic fluid, with kinematic self-similarity of the first kind, in $(2+1)$-dimensional spacetimes. In the case where the radial pressure vanishes,
