Lectures on Polyhedral Topology by J.R. Stallings

 “Lectures on Polyhedral Topology” by J.R. Stallings, of his lectures in TIFR 1967, is available online. It also has bits of my first research. I think that the appendix to Chapter seven is mine. And 8.9.3, the proof of s-cobordism with prescribed torsion is mine. I did not understand Stallings proof which used Stiefel-Whitney classes which I was not comfortable with at that time. I came up with the argument given here which is now standard, I think.
