The workshop is a part of the Simons semester program Varieties: $\mathbb{A}$rithmetic and $\mathbb{T}$ransformations held at IMPAN, Warsaw. The aim is to bring together people interested in learning the theory of $F$isocrystals in order to get a quick and intense start. The approach is to look at the recent results concerning Newton polygons of $F$isocrystals on abelian varieties from two different perspectives: geometric given by Tsuzuki and Tannakian provided in the paper by d'Addezio. We also plan to have three research level lectures by Marco d'Addezio, Christopher Lazda and Atsushi Shiho. For the precise program, please take a look below.
We encourage all interested people to volunteer to give one of the talks. We hope to establish the whole speaking squad by Sunday 21st Oct. If you want to book a spot, discuss the content of the lectures or ask any other question concerning the workshop's program please write to the organizers.
The workshop will take place in Institute of Mathematics, Polish Academy of Sciences, ul. Śniadeckich 8, Warsaw. The precise room number will be announced before the event.
Unfortunately, we cannot provide any financial support for the participants.
The meeting is partially funded by Banach Center.
The event is organized by Piotr Achinger (IMPAN Warsaw) and Maciej Zdanowicz (EPF Lausanne)
