LOL ... I had a very beautiful Danish girl who was an exchange student here and in my classes for a year back about 25 years ago. She was phenomenally brilliant, too. All the guys stayed in the class all year to "work" with her :D
I don't know of a text that focuses just on CW complexes, @Fernando. They're usually part of an algebraic topology or differential topology course/book.
Real analysis is hard, @Danny, and Rudin is not a book that is easily digested.
I teach all sorts of things, but recently every year I have been teaching a multivariable calculus/analysis/linear algebra combined course that I created. Also taught abstract algebra last year, differential geometry this year.
Munkres wrote a much more readable book on homology/cohomology (no fundamental group stuff) that talks about it. Hatcher's topology book is all the rage now, and you can download a .pdf free from his webpage.
No, no, @Danny. I finished my Ph.D. in 1979. I'm old.
So in the sequence $s_n = (-1)^{n+1}$ the subsequence $s_{2n-1}$ 'converges' to $+\infty$ and the subsequence $s_{2n}$ 'converges' to $-\infty$........kind of odd
@masfenix They're the space of all functions that are infinitely differentiable and both the function and the derivatives decrease faster than ANY power of $x$ as $x \to \pm \infty$
