Boundary regularity and Wiener-type criteria at infinity for nonlinear elliptic equations of $p$ -Laplace type

Anders Björn, Jana Björn, David Manolis

We study boundary regularity at the infinity point $\infty$ for nonlinear elliptic equations of $p$ -Laplace type in unbounded open sets $Ω \subset R^{n}$ . We con…

Semiregular and strongly irregular boundary points for nonlocal Dirichlet problems

Anders Björn, Jana Björn, Minhyun Kim

In this paper we study nonlocal nonlinear equations of fractional $(s, p)$ -Laplacian type on $R^{n}$ . We show that the irregular boundary points for the Dirichlet problem can…

The quasisuperminimizing constant for the minimum of two quasisuperminimizers in R^n

Anders Björn, Jana Björn, Ismail Mirumbe

It was shown in Björn--Björn--Korte ("Minima of quasisuperminimizers", Nonlinear Anal. 155 (2017), 264-284) that $u := min {u_{1}, u_{2}}$ is a $Q$ -quasisuperminimizer if $u_…
