Homology of Fibre Spaces,s which are connected by an exact triangle. Such a diagram is called an exact couple; the notion is due to Massey . The basic operation on exact couples, that of ., gives rise to a new exact couple. Hence the process can be iterated to obtain an infinite sequence of diagrams.

Homology with Local Coefficients, the function . as a cochain of . with coefficients in the abstract group .. The difficulty is that the isomorphisms . (.) ≈ . (.) are not uniquely defined; they depend on the choice of a homotopy class of paths joining . and ..

Textbook 1978 with the fundamental group and with singular homology theory, including the Universal Coefficient and Kiinneth Theorems. Some acquaintance with manifolds and Poincare duality is desirable, but not essential. Anyone who has taught a course in algebraic topology is familiar with the fact that a formi
