Abstract:
The main aim of the present paper is to disprove the Cohen-Lenstra-Martinet
heuristics in two different ways and to offer possible corrections. We also
recast the heuristics in terms of Arakelov class groups, giving an explanation
for the probability weights appearing in the general form of the heuristics. We
conclude by proposing a rigorously formulated Cohen-Lenstra-Martinet
conjecture.
