Question 1 in the appendix on CW complexes in Hatcher's Algebraic Topology book.

258 Views Asked by At

I am asked to show that a covering space of a CW-complex is also a CW-complex with cells projecting homeomorphically onto cells.

Do you have a reference for this question?

Thanks in advance.

You ask for a reference. The result was one of the basic facts on CW-complexes in JHC Whitehead's paper "Combinatorial Homotopy I". Bull. Amer. Math. Soc. 55 (1949) 213--245. (It is result (N) on p.231.) A proof is also given in Massey's book on "Algebraic topology".
