Event Details


The DIAMANT symposium of Spring 2023 will take place on Thursday 13 April in venue De Zalen van Zeven in Utrecht. Invited speakers are Yukako Kezuka (Institut de Mathématiques de Jussieu Paris) and Chloe Martindale (University of Bristol).

The Dutch Mathematical Congress (NMC2023) is held at Van Der Valk Hotel in Utrecht on 11 and 12 April and features a DIAMANT session on 11 April including invited speakers Olga Lukina (Leiden University) and Alberto Ravagnani (TU Eindhoven).

In the registration form (see below) there is an option to submit title and abstract. Alternatively, after registration, a title+abstract can be sent to symposiumdiamant@gmail.com at a later date.

Conference fee + accommodation

There is full DIAMANT support for DIAMANT members. DIAMANT members are full and associate professors listed here, as well as their research group members.

Non-vanishing theorems for central L-values
The conjecture of Birch and Swinnerton-Dyer is one of the principal problems in number theory, which remains largely open. The complex L-function which appears in the Birch–Swinnerton-Dyer formula has a p-adic nature, which led to the study of the p-part of the conjecture for each prime number p. The p-adic method of Iwasawa theory is one of the most powerful tools we currently have at tackling the p-part of the Birch–Swinnerton-Dyer conjecture. The case p = 2 is however excluded in nearly all of the classical literature, due to serious technical difficulties. We will prove non-vanishing theorems for the central values of the complex L-series of a large class of quadratic twists of the Gross elliptic curve. In particular, we obtain the finiteness of the Tate-Shafarevich group for these curves. The proof relies on developing Iwasawa theory at the prime 2. This is joint work with Yong-Xiong Li.
