Algebra and geometry online seminar 05-03-2021

[Francesco Galuppi]

Dear colleagues,

this is to advertise the weekly seminar of the Algebra and Geometry 
group of the University of Trieste. On Friday, March 5th at 10:30, 
Eleonora Romano (University of Genova) will talk about "Torus actions 
from the viewpoint of birational geometry".

We focus on complex, smooth, projective varieties admitting a 
non-trivial C*-action. We introduce a new approach to investigate such 
varieties, using instruments coming from birational geometry. In 
particular, we relate small bandwidth varieties with Atiyah flips and 
special Cremona transformations. We report recent classification results 
of small bandwidth varieties, with particular attention to the case of 
bandwidth 3. We finally discuss some  applications, in the framework of 
LeBrun-Salamon conjecture. This is a  joint project with G. Occhetta, L. 
Solá Conde and J. Wiśniewski.

The seminar will take place online. The Zoom link is

You are welcome to extend the invitation to anyone interested.

Best,
Francesco
