Deformation spaces Hom(�,G)/G of representations of the fundamental groupof a surfacein a Lie group G ad- mit natural actions of the mapping class group Mod�, preserving a Poisson structure. When G is compact, the actions are ergodic. In contrast if G is noncompact semisimple, the associated deforma- tion space contains open subsets containing the Fricke-Teichmuller space upon which Modacts properly. Properness of the Mod�- action relates to (possibly singular) locally homogeneous geomet- ric… Expand
