Title: Generic ultrafilters
Abstract: S. Todorcevic proved that given the presence of large
cardinals, selective ultrafilters are precisely ultrafilters
P(omega)/FIN-generic over L(R). We generalize this result. We provide a
characterization of P(omega)/I-generic ultrafilters over L(R) for an
arbitrary F_sigma ideal I.
This is a joint work with Jindra Zapletal.
