Title:       Higher Chow cycles on Abelian surfaces

Date:   Tue, Nov 13, 2012, 13:15 - 14:45

Place:  Seminar Room A

Abastract:

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.
