Strong Maximum Principles for Anisotropic Elliptic and Parabolic Equations [PDF]
Abstract We investigate vanishing properties of nonnegative solutions of anisotropic elliptic and parabolic equations. We describe the optimal vanishing sets, and we establish strong maximum principles.

Positive solutions for nonparametric anisotropic singular solutions [PDF]
We consider an elliptic equation driven by a nonlinear, nonhomogeneous differential operator with nonstandard growth. The reaction has the combined effects of a singular term and of a "superlinear" perturbation.

Entropy of Anisotropic Universe and Fractional Branes [PDF]
We obtain the entropy of a homogeneous anisotropic universe applicable, by assumption, to the fractional branes in the universe in the model of Chowdhury and Mathur. The entropy for the 3 or 4 charge fractional branes thus obtained is not of the expected

Searching for a preferred direction with Union2.1 data [PDF]
A cosmological preferred direction was reported from the type Ia supernovae (SNe Ia) data in recent years. We use the Union2.1 data to give a simple classification of such studies for the first time.

Minimal Stencils for Discretizations of Anisotropic PDEs Preserving Causality or the Maximum Principle [PDF]
Summary: We consider discretizations of anisotropic diffusion and of the anisotropic eikonal equation, on two-dimensional cartesian grids, which preserve their structural properties: the maximum principle for diffusion, and causality for the eikonal equation.

Anisotropic Stars in General Relativity [PDF]
We present a class of exact solutions of Einstein's gravitational field equations describing spherically symmetric and static anisotropic stellar type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor.

An overdetermined problem for the anisotropic capacity [PDF]
We consider an overdetermined problem for the Finsler Laplacian in the exterior of a convex domain in $\mathbb{R}^N$, establishing a symmetry result for the anisotropic capacitary potential. Our result extends the one of W. Reichel [Arch.
