A uniqueness result for functions with zero fine gradient on quasiconnected and finely connected sets

Anders Björn, Jana Björn

We show that every Sobolev function in $W_{loc}^{1, p} (U)$ on a $p$ -quasiopen set $U \subset R^{n}$ with a.e.-vanishing $p$ -fine gradient is a.e.-constant if and only i…

Boundary regularity for the porous medium equation

Anders Björn, Jana Björn, Ugo Gianazza +1

We study the boundary regularity of solutions to the porous medium equation $u_{t} = Δ u^{m}$ in the degenerate range $m > 1$ . In particular, we show that in cylinders the Dirichlet probl…
