日時: 11月15日 (木) 15:30-16:30
場所: 自然系学系棟 D509
タイトル: Higher Chow cycles on Abelian surfaces
講演者: Ramesh Sreekantan 氏 (The Indian Statistical Institute in Bangalore)
概要:
In this talk we use generalizations of beautiful classical geometric constructions of Kummer and Humbert to construct new higher Chow cycles on Abelian surfaces and K3 surfaces over p-adic local fields, generalising some work of Collino. The existence of these cycles is predicted by the poles of the local L-factor at p of the L-function of the Abelian surface. The techniques involve using some recent work of Bogomolov-Hassett and Tschinkel on the deformations of rational curves on K3 surfaces.
