Abstract

New characterizations of Bloch functions on a bounded symmetric domain in ℂn are given in terms of the intrinsic metrics. Various criteria for an M-harmonic function to be Bloch or little Bloch are obtained. These criteria establish the links between the M-harmonic Bloch and little Bloch functionsf and other notions including the Laplace-Betrami operator. We also study some basic properties of M-harmonic Bloch and little Bloch functions, extending previously known results for holomorphic functions. The space of M-harmonic functions contains the Poisson integrals of Borel measures and all pluriharmonic functions.
