Chabauty-Coleman-Kim
Organizers: Matteo Longo, Nicola Mazzari, Luca Mastella, Khai-Hoan Nguyen-Dang
Time: The seminar will be held on Friday, room 2BC60, from 15:00-16:00. The first talk will take place on October 22.
Zoom:
ID: 827 1490 1749
Passcode: Please ask one of organizers for more information
The first part of the seminar will deal with Chabauty-Coleman method focusing on Coleman’s p-adic integration theory.
The second part will explain how Kim’s method is a natural generalization of the classical Chabauty.
