• Conformal mapping

  by homeomorphisms: if f : X -> Y is a a homeomorphism, and X is simply connected, then so is f(X) now, given a simply connected domain U of C, then the invariance of domain theorem ensures that a 1-1 continuous map f : U --> C is a homeomorphism

• Bijection Proof

  is the same thing as showing that f is a closed map (takes closed sets to closed sets); that is, if A is closed in M, then we want to show (f^{-1})^{-1} (A) = f(A) is closed in N but if A < M is closed, then A is compact (a closed subset of

• Covering Maps : Let q: X->Y and r:Y->Z be covering maps; let p=(r(q(x))). Show if r^(-1)(z) is finite for each z in Z, p is a covering map.

  So q^-1[W_i] is a disjoint union of open sets O_i,j (j running), and each maps O_i,j is mapped homeomorpically by q onto V_i. We need to couple these facts.
