Anisotropic Improved Leray-Trudinger Inequality

Abstract

We establish a Leray- Trudinger Type inequality in the anisotropic setting induced by a strongly convex Finsler norm F. The result generalizes classical exponential integrability inequalities for Sobolev functions to the framework of anisotropic Sobolev spaces $W^{1,n}_0(\Omega)$, where the standard Euclidean norm is replaced by F and associated polar norm $F^o$. Moreover, in the class of anisotropically radial functions, we obtain the optimal constant in the spirit of Moser's sharp inequality.
