Morse theory is a standard concept used in the study of manifolds. PL-Morse theory is a variant of Morse theory developed by Bestvina and Brady that is used to study simplicial complexes. We develop an extension of PL-Morse theory to simplicial complexes equipped with an action of a group G. We will discuss some of the basic ideas in this theory and hopefully sketch proofs of some forthcoming results pertaining to the homology of the Torelli group.
