Is there any good guide on covering space for idiots? Like a really dumped down approach to it . As I have an exam on this, but don't understand it and it's like 1/6th of the exam.

So I'm doing Hatcher problem and stuck on 4.

  1. Construct a simply-connected covering space of the space $X \subset \mathbb{R}^3$ that is a union of a sphere and diameter.

All I can think of is just connecting a bunch of spheres in a line.

But, yeah pretty scared will fail my degree because of this. So I need a good guide of covering spaces that isn't Hatcher. The only other uses heavy category theory which is even worse to read.

    What about Munkres' "Topology" book, that has a second part with algebraic topology? I think it is very, very readable.2012-04-06
