In Riemannian geometry there are several notions of rank
defined for non-positively curved manifolds and with natural extensions
for groups acting on non-positively curved spaces.
The talk shall explain how various notions of rank behave for
mapping class groups of surfaces. This is joint work with J. Behrstock.
