Computation of Ext group

  1. Jul 26, 2010 #1
    1. The problem statement, all variables and given/known data
    Compute Ext(R,Z) where R is the real numbers and Z is the integers


    2. Relevant equations



    3. The attempt at a solution
    This is part of a problem is given in Hilton-Stammbach page 109; the previous parts of the problem asks to compute Ext(Q,Z) and Hom(Q,Q/Z); I have computed both and they are both isomorphic to R
