A Boundary Estimate for Singular Sub-Critical Parabolic Equations
Ugo Gianazza, Naian Liao
We prove an estimate on the modulus of continuity at a boundary point of a cylindrical domain for local weak solutions to singular parabolic equations of -laplacian type, with $…

Self-improving property of the fast diffusion equation
Ugo Gianazza, Sebastian Schwarzacher
We show that the gradient of the -power of a solution to a singular parabolic equation of porous medium-type (also known as fast diffusion equation), satisfies a reverse Hölder…

A Boundary Estimate for Degenerate Parabolic Diffusion Equations
Ugo Gianazza, Naian Liao
We prove an estimate on the modulus of continuity at a boundary point of a cylindrical domain for local weak solutions to degenerate parabolic equations of -laplacian type. The…
