*ONLINE SEMINAR ANNOUNCEMENT/REMINDER *
Dear all, this is a reminder for the next seminar on K3 surfaces.
Speaker: Alejandra Rincón Hidalgo (ICTP)
Title: Roitman's Theorem for K3 surfaces
Abstract: The aim of this talk is to prove Roitman's theorem for a K3
surface X i.e. that CH^2(X) is torsion free.
We first start by studying the monodromy representation of a Lefschetz
fibration. We then reduced the main problem to study torsion points on
J(C) for a nonsingular curve C very ample on X. Since C belongs to a
Lefschetz pencil on X, we use its monodromy representation to study
cycles on C.
If time permits we give an alternative approach for elliptic K3 surfaces.
