Wall differential topology pdf

The appendix covering the bare essentials of pointset topology was covered at the beginning of the semester parallel to the introduction and the smooth manifold chapters, with the emphasis that pointset topology was a tool which we were going to use all the time, but that it was not the subject of study this emphasis was the reason to put.
