Complex Analysis-Isomorphisms

  1. Aug 10, 2010 #1
    1. The problem statement, all variables and given/known data
    I need to find isomorphisms from D to R in the next cases:

    1. [tex] D=(z: 0<|z|<1)$ , $ R=(z:1<|z|<2) [/tex]
    2. [tex] D= (z: \frac{3 \pi}{4} <argz< \pi , |z|>2 )$ , $R= (z:Rez<0,0<Imz< \pi) [/tex]
    3. [tex] D=(z:0<Imz<2)-(z:z=x+i:x \leq -1) $ , $R= (z: |z|<1 , Imz>0) [/tex].

    2. Relevant equations

    3. The attempt at a solution

    I've no idea about these three cases...
    Hope you'll be able to help me!

    I don't know how to solve the latex problems...It should write it ok... I don't know what I did wrong
