titolo:
“Connected components in
families”
Abstract
In
this talk, I will give some remarks on the moduli of relative connected and
irreducible components of a scheme flat and of finite presentation over a base
scheme S. In particular I will introduce various candidates of moduli spaces,
provide existence and non-existence results, and in the proper case compare them
with the Stein factorization.
Motivation
for these considerations come from the study of the Picard functor and the
moduli of curves with group action.
Tutti gli interessati
sono invitati a partecipare.
