Covering Spaces : Compact Hausdorff Spaces and Homomorphisms
(proof1)
Let and Y be topological spaces and suppose there is a surjective continuous map f : X Y which satisfies the following condition: for each x Y, there is an open neighborhood of such that
• f -1 (U) is a disjoint union of open sets A

Path connected problems
Show that if f:X->Y is a continuous map between topological spaces and X is path connected, then the image f(Y) is also path connected.

7) If alpha: X_1 ---> X_2 and beta: X_2 ---> X_3 are continuous functions of compact topological spaces, explain why (beta is in alpha)* = alpha* is in beta*
8) Hence prove that if gama: X --> Z is a homeomorphism of compact topological spaces
