Existence and almost uniqueness for $p$ -harmonic Green functions on bounded domains in metric spaces

Anders Björn, Jana Björn, Juha Lehrbäck

We study ( $p$ -harmonic) singular functions, defined by means of upper gradients, in bounded domains in metric measure spaces. It is shown that singular functions exist if and only…

Boundary regularity for $p$ -harmonic functions and solutions of obstacle problems on unbounded sets in metric spaces

Anders Björn, Daniel Hansevi

The theory of boundary regularity for $p$ -harmonic functions is extended to unbounded open sets in complete metric spaces with a doubling measure supporting a $p$ -Poincaré inequali…
