My very own copy of Mosher and Tangora! It arrived on my desk recently, a reprint of the 1968 text. The algebraic topology community owes a great deal of thanks to Dover for picking up this classic.
What more needs to be said? Not much! If you’re an algebraic topologist or want to be one, pick up a copy today. If, on the other hand, the words “cohomology” and “homotopy” don’t roll off your tongue, there’s no need to crack the spine here.
This is a very readable, thin volume, which does quite a bit without trying to do too much. The book provides the grounding necessary for the methods discussed, while refraining from excruciating detail. For example, before the Serre spectral sequence is used, there is a concise set up of spectral sequences and fibre spaces. This approach lends greatly to the readability of the text. The particular cohomology operations known as the Steenrod squares form the backbone of this book, but unlike Steenrod and Epstein’s earlier book on cohomology operations, Eilenberg-MacLane spaces are also prominent here. The Adams spectral sequence and some calculuations regarding the stable homotopy groups of spheres are also nicely presented.
