We consider general problems of which spaces can be the fixed point sets of a (semi-free) action of a given finite group on a compact space of prescribed homotopy type. We treat such questions for finite cell complexes, for compact ANR's, and allowing these spaces to be non-simply connected.

This is joint work with Shmuel Weinberger and Min Yan.
