摘要

This article is an attempt to understand harmonic and holomorphic maps between two bounded symmetric domains in special situations.We study foliations associated to a lattice-equivariant harmonic map of small rank from a complex ball to another.The result is related to rigidity of some complex two ball quotients.Some open questions are raised as well.
