I'm looking to do some independent reading and I haven't been able to find rough prerequisites for Differential Topology at the level of Milnor or Guillemin and Pollack.
Is a semester of analysis (Pugh) and a semester of topology (Munkres) enough to make sense of most of it or should I take a second semester of analysis first?
If you understand some set theory, you might like to use Kinsey's "Topology of Surfaces", which is what my class used as a pre/corequisite when we were studying Milnor's "Topology from the Differentiable Viewpoint".
They complement each-other nicely; Kinsey is tutorial-like and you could probably get through five pages in a day, whereas Milnor is terse and one page a day (depending on the page!) is a fast self-study pace.
