The shape of a group---connections between shape theory and the homology of groups
One-parameter Fixed Point Theory.
Compacta weak shape equivalent to ANR's
Compacta with the shape finite complexes
Fixed point theory and the K-theoretic trace
The relationship between fixed point theory and K-theory is explained, both classical Nielsen theory (versus ) and 1-parameter fixed point theory (versus ). In particular, various zeta functions associated with suspension flows are shown to come in a natural way as “traces” of “torsions” of Whitehead and Reidemeister type.
