Algebra and geometry seminar 12-02-2021

[Francesco Galuppi]

Dear colleagues,

this is to advertise the weekly seminar of the Algebra and Geometry 
group of the University of Trieste. On Friday, February 12th at 10:30, 
Milena Wrobel (University of Oldenburg) will talk about "Intrinsic 
Grassmannians".

Abstract: Generalizing the well-known weighted Grassmanians introduced 
by Corti and Reid, we study certain geometric invariant theory quotients 
of the affine cone over the Plücker embedding of Gr(k,n). More 
precisely, we consider normal projective varieties whose Cox ring is 
defined by the Plücker ideal I_{k,n}. For k = 2, we classify the smooth 
Fano ones having Picard number two and give a concrete formula to 
compute their number for arbitrary n.

The seminar will take place online. The Zoom link is

You are welcome to extend the invitation to anyone interested.

Best,
Francesco
