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.

Everyone is welcome to attend!
