Regularity for Doubly Nonlinear Equations in the Mixed Regime

Simone Ciani, Eurica Henriques, Mariia Savchenko +2

We study the local Hölder continuity of nonnegative solutions to doubly nonlinear equations by introducing a new technique that allows us to treat the cases where the equation is b…

Qualitative properties of solutions to parabolic anisotropic equations: Part I -- Expansion of positivity

Simone Ciani, Eurica Henriques, Mariia Savchenko +1

We prove expansion of positivity and reduction of the oscillation results to the local weak solutions to a doubly nonlinear anisotropic class of parabolic differential equations wi…

Qualitative properties of solutions to parabolic anisotropic equations: Part II. The anisotropic Trudinger's equation

Simone Ciani, Eurica Henriques, Mariia O. Savchenko +1

We study the local regularity properties of weak solutions to a special class of anisotropic doubly nonlinear parabolic operators, whose prototype is the anisotropic Trudinger's eq…

Parabolic De Giorgi classes with doubly nonlinear, nonstandard growth: local boundedness under exact integrability assumptions

Simone Ciani, Eurica Henriques, Mariia O. Savchenko +1

We define a suitable class of functions bearing unbalanced energy estimates, that are embodied by local weak subsolutions to doubly nonlinear, double-phase, Orlicz-…

The weak Harnack inequality for unbounded minimizers of elliptic functionals with generalized Orlicz growth

Simone Ciani, Eurica Henriques, Igor i. Skrypnik

In this work we prove that the non-negative functions , for some , belonging to the De Giorgi classes \begin{equation}\label{eq0.1} \fint\limits_{B_{r(1-σ)…

Fine boundary continuity for degenerate double-phase diffusion

Simone Ciani, Eurica Henriques, Igor Skrypnik

We study the boundary behavior of solutions to parabolic double-phase equations through the celebrated Wiener's sufficiency criterion. The analysis is conducted for cylindrical dom…
