Geometria On the Morin problem Grzegorz Kapustka 16-02-2017 - 14:30 AULA 211 - Largo San Leonardo Murialdo,1 - Roma
I will discuss the problem of classification of finite complete families of incident planes in P^5. First i will present a construction of a complete family of incident planes of maximal cardinality 20 (a joint work with M.Donten-Bury, B.van Geemen, M.Kapustka, J. Wisniewski). Then show that the Morin problem is equivalent to the problem of classification of nodal (2,2) divisors in P2xP2. The methods consist of studying projective models of special hyper-Kaehler fourfolds. |
