Abstract

On two subsurfaces of a Riemann surface divided by a pp-Weil-Petersson curve γ\gamma, we consider the spaces of harmonic functions whose pp-Dirichlet integrals are finite in the complementary domains of γ\gamma. By requiring the coincidence of boundary values on γ\gamma, we establish a correspondence between the harmonic functions in these Banach spaces. We analyze the operator arising from this correspondence via the composition operator acting on the Banach space of pp-Besov functions on the unit circle.
