Title: A construction of equivariant bundles on the space of symmetric forms

Abstract: I will report on a recent joint work with D. Faenzi and P.  
Lella, where we give a new construction of indecomposable
vector bundles on the space of symmetric forms of degree d in n+1  
variables, which areequivariant for the action of the complex Lie  
group SL_{n+1}, and moreover admit an equivariant free resolution of  
length 2.
For n=1, we obtain new examples of indecomposable vector bundles of  
rank d-1 on P^d, which are moreover equivariant for SL_2.
The presentation matrix of these bundles attains the bound for  
matrices of linear forms of constant rank for that size and rank.
