hey guys
im trying to prove a fact. it is supposed to be really easy but I am having some trouble. this is it:
http://en.wikipedia.org/wiki/Topological_manifold
"It follows from invariance of domain that Euclidean neighborhoods are always open sets."
Invariance of Domain - http://en.wikipedia.org/wiki/Invariance_of_domain
could anyone help out ?
