[Dottorcomp] Seminari di Geometria e Algebra - mercoledì 8 ottobre 2025

[Lidia Stoppino]

Carissimi,

il giorno mercoledì 8 ottobre  2025, alle ore 16,15  precise 
in aula Beltrami 

Enrico Fatighenti (Università di Bologna) 

terrà un seminario dal titolo:
Modular vector bundles on hyperkähler manifolds.

Abstract: We exhibit examples of slope-stable and modular vector bundles on a hyperkähler manifold of K3^[2]-type. These are obtained by performing standard linear algebra constructions on the examples studied by O’Grady of (rigid) modular bundles on the Fano varieties of lines of a general cubic 4-fold and the Debarre-Voisin hyperkähler. Interestingly enough, these constructions are almost never infinitesimally rigid, and more precisely we show how to get (infinitely many) 20 and 40 dimensional families. This is a joint work with Claudio Onorati.  Time permitting, I will also present a joint work with Alessandro D'Andrea and Claudio Onorati on a connection between discriminants of vector bundles on smooth and projective varieties and representation theory of GL(n).


Turtti gli interessati sono invitati a partecipare.
