Algebra and geometry seminar 14-05-2021

[Francesco Galuppi]

Dear colleagues,

this is to advertise the weekly seminar of the Algebra and geometry 
group of University of Trieste. On Friday, May 14th at 10:30, Sara 
Torelli (University of Hannover) will talk about "Holomorphic one forms 
on moduli of curves".

It is a classical result from the sixties that the moduli space of 
smooth projective curves Mg does not have non-trivial closed holomorphic 
1-forms, for genus g > 2. In the talk I present a stronger result 
recently proven in collaboration with F. Favale and G.P. Pirola that the 
moduli space Mg does not have holomorphic 1-forms at all, even not 
closed, at least for genus g ≥ 5. Time permitting, I will then discuss 
further applications of the developed techniques.

The seminar will take place online. The Zoom link is

You are welcome to extend the invitation to anyone interested.

All the best,
Francesco
