So I have solved the second problem, the trick was simply using the cauchy-reimann equations to break my one expression with two derivatives on each side into two expressions with one derivative on each side.

The first problem still escapes me ):

No, that part is true (since hi-1 is one-to-one). But (U1 - f1) U U2 may not be the same as (U1 U U2) - f1. The former is what you get when you take W1 U U2, and the latter is Y - f1, which is what you want. Oooh. That is a problem then. I can't seem to find a way to somehow join up all the homeomo...

Very much my bad. I think that statement was actually supposed to be W_i is dense and open in U_i. Thus Union of all U_j s.t j != i, union with W_i is dense and open in Y.

Then, letting Y be the union of all U_i's, h_i^-1(V_i-S_i) := W_i is dense and open in U_i, and thus is dense and open in Y. The bolded statement is false. Draw some pictures!
