On the existence of solutions to some singular parabolic free boundary problems

Alessandro Audrito, Tomás Sanz-Perela

We construct nonnegative weak solutions to the singular parabolic free boundary problem \[ \partial_t u - Δu = - \frac{\mathrm{d}}{\mathrm{d} u} u_+^γ, \] where , $u_+…

Schauder estimates for parabolic equations with degenerate or singular weights

Alessandro Audrito, Gabriele Fioravanti, Stefano Vita

We establish some and regularity estimates for a class of weighted parabolic problems in divergence form. The main novelty is that the weights may vanish or exp…

Elliptic regularization of some semilinear parabolic free boundary problems

Alessandro Audrito, Tomás Sanz-Perela

We prove existence of strong solutions to a family of some semilinear parabolic free boundary problems by means of elliptic regularization. Existence of solutions is obtained in tw…

Regularity theory for fully nonlinear parabolic obstacle problems

Alessandro Audrito, Teo Kukuljan

We study the free boundary of solutions to the parabolic obstacle problem with fully nonlinear diffusion. We show that the free boundary splits into a regular and a singular part:…

Convergence in relative error for the Porous Medium equation in a tube

Alessandro Audrito, Alejandro Gárriz, Fernando Quirós

Given a bounded domain and , we study the long-time behaviour of solutions to the Porous Medium equation (PME) posed in a tube \[ \partial_tu = Δu^m…
