Maximal Sobolev regularity of the stress tensor for the symmetric gradient p-Laplace system

Analysis of PDEs 2026-03-19 v1

Abstract

The symmetric pp-Laplace operator enters various models in mathematical physics, such as incompressible materials with power-type hardening and non-Newtonian fluids. In this work, second-order differentiability properties of solutions to the symmetric pp-Laplace system are established. They are formulated as maximal Sobolev regularity of the nonlinear stress tensor for locally square integrable right-hand sides.
