Spherical objects on K3 surfaces and Chow groups
Abstract: Spherical objects form a distinguished discrete set of objects in
the derived category of coherent sheaves on a K3 surface. The subcategory
generated by them is of particular interest for the group of
autoequivalences as well as for the Chow group of the surface. I will in
particular discuss its relation to the Bloch-Beilinson conjecture predicting
that over a number field the Chow group is finite dimensional.
