Let Rν, ν = I, II, III, IV,
be the 4 types of the classical Cartan domains and let ℰ(Rν) denote the
class of solutions u of the Laplace’s equation Δu = 0 corresponding to the
Bergman metric of Rν which satisfy certain regularity conditions specified
below.
In this note we give a distortion theorem for functions which are holomorphic in
Rν and omit the value 0 there, and an application which leads to an interesting
property of integral functions omitting the value 0. The tools used here are the
generalized Harnack inequality for functions in the class ℰ(Rν) and the classical
theorem of Liouville for integral functions.
