Abstract: In 1971, Davenport and Heilbronn proved the celebrated theorem determining the average of $3$-torsion in class groups of quadratic extensions. In this talk, we will study the average of $3$-torsion in class groups of $2$-extensions, which are towers of relative quadratic extensions. As an example, we determine the average of $3$-torsion in class groups of $D_4$ quartic extensions. This is a joint work with Robert J. Lemke Oliver and Melanie Matchett Wood.
