Abstract

The aim of this paper is to study the formal structure of the Puppe sequence for half-exact functors ([3],5.6). We work with the notion of homotopy system in a category ([7],1.1). We combine the techniques of [7] and [8] using weak pushouts in the homotopy category and the algebraic structure of the fundamental groupoid systematically.
