Abstract
Let L/k be a finite Galois extension of number fields with Galois group G (not necessarily abelian). For every odd prime p satisfying certain mild technical hypotheses, we use values of Artin L-functions to construct an element in the centre of the group ring Z_{(p)}[G] that annihilates the p-part of the class group of L. This is joint work with David Burns (King's College London).
