Abstract Homotopy And Simple Homotopy Theory - Kamps, K Heiner (Fern Univ, Germany) a Porter, Timothy (Univ Of Wales Bangor, Uk)

Discusses abstract homotopy theory, which is based on the observation that analogues of much of topological homotopy theory and simple homotopy theory exist in many other categories, such as spaces over a fixed base, groupoids, chain complexes and module categories.
