Ambrus Pal (Imperial College)


In spite of their importance, there has not been a real breakthrough on the conjectures of Artin-Tate, Parshin, Tate and Beilinson on algebraic cycles and related K-groups in positive characteristic since they were formulated.
In my talks I will try to describe a program whose eventual goal is to make progress on these conjectures via formulating a refined set of conjectures which give hints where we should look for those algebraic cycles which are predicted by the original conjectures, and hence enable us to find them.



○また、本連続講義の翌々週、 Pal氏は東京大学数理科学研究科である「モチーフの勉強会第3回」 において 「A p-adic Langlands correspondence in characteristic p」 という題目で講演することも付言致します。

19(Tue)/June 15:00--16:30 at room 202:
「Non-archimedean L-functions and periods」
Abstract: I will describe an analogue of the p-adic L-function of elliptic curves and show how one may use modular parametrizations by Drinfeld modular curves to prove an analogue of the exceptional zero conjecture.

20(Wed)/June 15:00--16:30 at room 009:
「Rigid-analytic regulators」
Abstract: The aim of this second talk is to demonstrate that there is a rich theory of rigid analytic regulators which are much more closely analogous to usual theory of regulators in characteristic zero than the cohomological constructions used in the above-mentioned set of conjectures.

21(Thu)/June 15:00--16:30 at room 009:
「An analogue of Beilinson's theorem on K2 of elliptic curves」
Abstract: I'll will talk about a refined non-archimedean analogue of the result in the title for elliptic curves over function fields of one variable which involves the regulator introduced in the previous talk. Hopefully the audience will see that we are on the right track since once the basic definitions are made it is very straightforward to find the analogue of every step in the classical situation.

22(Fri)/June 15:00--16:30 at room 115:
「Refined conjectures of the type of Beilinson and Swinnerton-Dyer-Birch」
Abstract: Depending on how much time is left after I'm finished with the previous subject, I will talk about some general conjectures for elliptic curves which are in some sense better analogues of the classical conjectures in positive characteristic and discuss what can be done about them.
