Algebra and geometry online seminar 26-02-21

[Francesco Galuppi]

Dear colleagues,

this is to advertise the weekly seminar of the Algebra and Geometry 
group of the University of Trieste. On Friday, February 26th at 10:30, 
Diletta Martinelli (University of Amsterdam) will talk about "Gale 
duality, blowups and moduli spaces".

The Gale correspondence provides a duality between sets of n points in 
projective spaces P^s and P^r when n=r+s+2. For small values of s, this 
duality has a remarkable geometric manifestation: the blowup of P^r at n 
points can be realized as a moduli space of vector bundles on the blowup 
of P^s at the Gale dual points. We explore this realization to describe 
the birational geometry of blowups of projective spaces at points in 
very general position. We will focus in particular on the cases where 
the blowup fails to be a Mori Dream Space, reporting on a joint work 
with Carolina Araujo, Ana-Maria Castravet and Inder Kaur.

The seminar will take place online. The Zoom link is

You are welcome to extend the invitation to anyone interested.

Best,
Francesco
