WebSURVEY ON CLASS FIELD THEORY 3 This solves the problem of describing the abelianized fundamental group ˇ 1(X)ab in terms of geometric data attached to X. Unfortunately, the class module is di cult to understand and, in particular, contains a cohomology group. It is therefore desirable to nd a more direct description. WebIf a(z)∗ = a(z), then we can assume that A]z = Az . To prove Theorem 8.2, we assume N = 1 and again proceed as in [11]. The proof of the theorem will follow right away from the following lemma. Let us fix some notation before proceeding with the proof. We begin by choosing A(z) as in Proposition 8.1. We may assume also that A(z) = IN .
