The weak Harnack inequality and the rigidity of the anisotropic Trudinger's equation

Simone Ciani, Mattia Galeotti, Igor Skrypnik

The paper establishes a local weak Harnack inequality for nonnegative weak super‑solutions of the anisotropic Trudinger equation and uses it to derive a Harnack inequality without…

Harnack estimates for the nonlocal Trudinger equation

Simone Ciani, Kenta Nakamura

We carry on a study of the point-wise regularity theory for the nonlocal Trudinger equation, with measurable and bounded singular kernel. We establish refined quantitative upper bo…

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…

Integral Harnack estimates and the rate of extinction of singular fractional diffusion

Filippo M. Cassanello, Simone Ciani, Antonio Iannizzotto

We prove several integral Harnack-type inequalities for local weak solutions of parabolic equations with measurable and bounded coefficients, describing singular s-fractional p-Lap…

Widely degenerate anisotropic diffusion: local boundedness and semicontinuity

Pasquale Ambrosio, Simone Ciani, Giovanni Cupini

We investigate the regularity of local weak solutions to evolution equations of the form \[ \partial_{t}u\,=\,\sum_{i=1}^{n}\,\partial_{x_{i}}\left[a_{i}(x,t)\,(\vert\partial_{x_{i…

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…
