Asymptotics for $6$-torsion and $D_6$-extensions

Number Theory 2025-12-29 v1

Abstract

We prove a composite case of the Cohen--Lenstra--Gerth heuristics. Specifically, we establish an asymptotic for the average 66-torsion of the class group of quadratic number fields. We also prove Malle's conjecture for Galois D6D_6-extensions.
