Goldman and colleagues consider moduli spaces of actions of discrete groups on hyperbolic space. Spaces of PSL(2,C)-representatives of fundamental groups of surfaces of negative Euler characteristic are natural objects upon which mapping class groups and related automorphism groups act, they say, and arise as deformation spaces of (possibly singular) locally homogeneous geometric structures on surfaces. They relate the interpretation in terms of geometric structures to the dynamics of automorphism groups. Annotation ©2019 Ringgold, Inc., Portland, OR (protoview.com)
