Quasicontinuity of $N^{1, \infty}$ functions and the Vitali-Carathéodory property on general metric spaces

Anders Björn, Jana Björn

This note is a follow up on our recent paper with L. Malý (to appear in Rev. Mat. Complut.). We provide a simple example of a compact metric space $P$ for which $L^\infty…

Barriers, Barenblatt solutions and regularity of soda can domains for the heat equation and nonlinear $p$ -parabolic equations

Anders Björn, Jana Björn

In this paper we study when the origin $(0, 0)$ is a regular (or irregular) boundary point for the so-called soda can domains of the type \[ Θ_{l,θ}:= \{(x,t) \in \mathbf{R}^{n+1}:…
