Venerdì 13 novembre 2020, alle ore 10,30, Ada Boralevi del Politecnico di Torino terrà un seminario dal titolo:
"Matrices of constant rank, quadric surfaces, Pfaffian hypersurfaces"
Abstract: I will report on a recent joint work with M.L. Fania and E. Mezzetti, where we studied smooth quadric surfaces in the Pfaffian hypersurface in P^14, not intersecting the Grassmannian G(1,5). Such surfaces correspond to quadratic systems of skew-symmetric matrices of size 6 and constant rank 4, and give rise to a globally generated vector bundle E on the quadric. I will describe these bundles and their geometry, explaining the different techniques that we used.
I seminari si terranno online, sulla piattaforma Zoom.
