Venerdì 27 novembre 2020, alle ore 10,30, Francesco Bastianelli (Università di Bari) terrà un seminario dal titolo:
Subvarieties of general hypersurfaces and their degree of irrationality
Abstract: I will be interested in discussing various birational invariants describing how a given variety X is far from being rational. After introducing these invariants, I will focus on the case where X is a general hypersurface of large degree in the complex projective space. In particular, I will report on recent results in collaboration with C. Ciliberto, F. Flamini and P. Supino, concerning the least degree of irrationality of irreducible subvarieties of X of fixed dimension passing through a general point of X.
I seminari si terranno online, sulla piattaforma Zoom.
