Archivio Istituzionale della RicercaWe study smooth quadric surfaces in the Pfaffian hypersurface in P-14 parameterizing 6 x 6 skew-symmetric matrices of rank at most 4, not intersecting its singular locus. 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. Weanalyse these bundles and their geometry, relating them to linear congruences in P-5.

Abstract
We study smooth quadric surfaces in the Pfaffian hypersurface in P-14 parameterizing 6 x 6 skew-symmetric matrices of rank at most 4, not intersecting its singular locus. 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. Weanalyse these bundles and their geometry, relating them to linear congruences in P-5.
