ABSTRACT

Let G be a graph, digraph or multigraph and let b be a positive
integer. The set of subgraphs of G for which every node has
degree at most b forms a simplicial complex. Some important
special cases which have arisen in various contexts in the recent
literature are the matching complex (G is a complete graph and b=1)
and the chessboard complex (G is a complete bipartite graph and b=1).
I will present some recent results on the homology of these
complexes. In particular, the representation of the symmetric group
on complex homology and torsion in integral homology will be discussed.
