Regularity for Doubly Nonlinear Equations in the Mixed Regime

Analysis of PDEs 2026-02-11 v1

Abstract

We study the local H\"older continuity of nonnegative solutions to doubly nonlinear equations by introducing a new technique that allows us to treat the cases where the equation is both singular and degenerate, up to specific Barenblatt numbers. Our argument relies on a new integral L1L^1-L1L^1 Harnack estimate, of independent interest.
