Abstract
Using an analogue of Serre’s open image theorem for elliptic curves with complex multiplication, one can associate to each CM elliptic curve E defined over a number field F a natural number I(E/F) which describes how big the image of the Galois representation associated to E is. We show how one can compute I(E/F), using a closed formula that we obtain from the classical theory of complex multiplication.
