Abstract
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.

In [Y, p. 1146, l. 35], it is stated that ���P���#T2 has a two-fold cover that is T2���. This is a mistake. As a result, [Y, Theorem 4.2] should be corrected as follows. The numbering of the references follows [Y].
