WebShintani’s zeta function enumerates class numbers of binary cubic forms. It is a degree 4 zeta function, which plays an important role in the proof of the Davenport-Heilbronn Theorem counting cubic elds ordered by discriminant. We prove a subconvex estimate for the zeta function, answering a question of Frank Thorne. Joint work with Eun Hye Lee.
