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

Everyone is welcome to attend!
