This is a continuation of our study [A stably free nonfree module and its relevance for homotopy classification, case [math] , Algebr Geom Topol 5 (2005) 899–910] of a family of projective modules over [math] , the generalized quaternion (binary di

The paper constructs an `exotic' algebraic 2-complex over the generalized quaternion group of order 28, with the boundary maps given by explicit matrices over the group ring. This result depends on showing that a certain ideal of the group ring is st

We consider spines of spherical space forms; i.e., spines of closed oriented 3-manifolds whose universal cover is the 3-sphere. We give sufficient conditions for such spines to be homotopy or simple homotopy equivalent to 2-complexes with the same fu
