terrà un seminario dal titolo:



*“**Berkovich approach to degenerations of hyper-Kähler varieties**”*



*Abstract:*

To a degeneration of varieties, we can associate the dual intersection
complex, a topological space that encodes the combinatoric of the central
fiber and reflects the geometry of the generic fiber. In this talk I will
show how the techniques of Berkovich geometry give an insight in the study
of the dual complexes. In this way, we are able to determine the
homeomorphism type of the dual complex of some degenerations of
hyper-Kähler varieties. The results are in accordance with the predictions
of mirror symmetry, and the recent work about the rational homology of dual
complexes of degenerations of hyper-Kähler varieties, due to Kollár, Laza,
Saccà and Voisin. This is joint work with Morgan Brown.



Tutti gli interessati sono invitati a partecipare.
