Applications of $p$-harmonic transplantation for functional inequalities involving a Finsler norm

Abstract

In this paper, we prove several inequalities such as Sobolev, Poincaré, logarithmic Sobolev, which involve a general norm with accurate information of extremals, and are valid for some symmetric functions. We use Ioku's transformation, which is a special case of $p$-harmonic transplantation, between symmetric functions.
