Semiregular and strongly irregular boundary points for -harmonic functions on unbounded sets in metric spaces
Anders Björn, Daniel Hansevi
The trichotomy between regular, semiregular, and strongly irregular boundary points for -harmonic functions is obtained for unbounded open sets in complete metric spaces with a…

Boundary regularity for -harmonic functions and solutions of obstacle problems on unbounded sets in metric spaces
Anders Björn, Daniel Hansevi
The theory of boundary regularity for -harmonic functions is extended to unbounded open sets in complete metric spaces with a doubling measure supporting a -Poincaré inequali…
