Bloch estimates in non-doubling generalized Orlicz spaces

Analysis of PDEs 2022-09-27 v2

Abstract

We study minimizers of non-autonomous functionals \begin{align*} \inf_u \int_\Omega \varphi(x,|\nabla u|) \, dx \end{align*} when φ\varphi has generalized Orlicz growth. We consider the case where the upper growth rate of φ\varphi is unbounded and prove the Harnack inequality for minimizers. Our technique is based on "truncating" the function φ\varphi to approximate the minimizer and Harnack estimates with uniform constants via a Bloch estimate for the approximating minimizers.
