Deformations of morphisms of locally free sheaves

Abstract
In this talk, we devote our attention to infinitesimal deformations of morphisms of locally free sheaves over a smooth projective variety. In particular, we describe a differential graded Lie algebra controlling these deformations over any algebraically closed field of characteristic zero. As an application, we analyse deformations of a locally free sheaf together with a subspace of its global sections. This is based on a collaboration with Elena Martinengo.
