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…

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…

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…

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-…

On the continuity of solutions to the anisotropic -Laplacian with lower order term

Mariia Savchenko, Igor Skrypnik, Yevgeniia Yevgenieva

We establish the continuity of bounded solutions to the anisotropic elliptic equation $$-\sum\limits_{i=1}^N\Big(|u_{x_i}|^{p_i-2} u_{x_i}\Big)_{x_i}=f(x),\quad x\in Ω,\quad f(x)\…
