Title:  Hochschild homology relative to a family of groups

Abstract:  We define the Hochschild homology groups of a group ring ZG
relative to a family of subgroups F of G. These groups are the
homology groups of a space which can be described as a homotopy
colimit, or as a configuration space, or, in the case F is the family
of finite subgroups of G, as a space constructed from stratum
preserving paths. This is joint work with David Rosenthal.
