Dr. Simone Marchesi (Università degli Studi di Milano
and  Universidad Complutense de Madrid) will give a talk
on

Jumping pairs in Steiner bundles

on Thursday, February 23, at 4:30 pm in Room 136,
SISSA Building A.

Abstract: In this talk we will present Steiner and Schwarzenberger
bundles on the Grassmannians and show the theory that relates them. In
the first part we will define the two families of bundles mentioned
before and study their properties. We will introduce then the concept
of jumping pair for a Steiner bundle and we will study the dimension
of the jumping locus of the bundle. Finally, we will give a complete
classification of Steiner bundles on the Grassmannian whose jumping
locus has maximal dimension and will describe them as
Schwarzenberger bundles.
