This monograph is a survey of some of the "classical" results and techniques as well as more recent developments in the theory of homology of local rings.
The homological approach to commutative ring theory officially begins in 1890 with Hilbert's tlleory of syzygies, and is extended through the work of Koszul and Cartan in the early 1950's. These pioneering efforts opened the way for the theory of homological dimension.Table of Contents.
