Almost Lipschitz regularity for solutions of elliptic equations with discontinuous coefficients

Raffaella Giova, Antonio Giuseppe Grimaldi, Stefania Russo

We are interested in the local higher integrability of solutions to elliptic equations with linear growth of the form Under a Besov regularity assump…

Regularity for Minimizers of non Autonomous Singular Functionals with Anisotropic Growth

Albert Clop, Antonia Passarelli di Napoli, Stefania Russo

We establish the higher differentiability of the local minimizers to a class of non autonomous convex integral functionals satisfying anisotropic subquadratic growth conditions, th…

Regularity for minimizers of degenerate, non-autonomous, orthotropic integral functionals

Antonio Giuseppe Grimaldi, Stefania Russo

We prove the higher differentiability of integer order of locally bounded minimizers of integral functionals of the form \begin{equation*} \mathcal{F}(u,Ω):= \,\sum_{i=1}^{n} \dfr…

Weak comparison principle for widely degenerate elliptic equations

Antonio Giuseppe Grimaldi, Stefania Russo

We prove a comparison principle for local weak solutions to a class of widely degenerate elliptic equations of the form \begin{equation} -\text{div} \left( \left(|Du|-1 \right)^{p-…

Higher Differentiability of Minimizers for Non-Autonomous Orthotropic Functionals

Stefania Russo

We establish the higher differentiability for the minimizers of the following non-autonomous integral functionals \begin{equation*} \mathcal{F}(u,Ω):= \, \int_Ω\sum_{i=1}^{n} \,…
