Better also to try to go for a single objective, it is so easy to be distracted by all those notions and lose focus. I'm just a mathematics hobbyist, and I still have no problem grasping the content, while you can really appreciate the mathematical rigour. For example, a normal surface can only have isolated singularities — the singular locus can’t contain a curve. Show that for any continuous map between topological spaces, there exists a map such that the following holds:? ? for two co 1) Prove that the map GIVEN BY is a homomorphism between the real line and open interval (-1,1). 2) Let be the map given by a) show that f is a bijection map b) show that f is a continuous map c) If f a homomorphism?
