[Dottorcomp] Insalate di Matematica - A. Zheng 30/11/22

[Mbs Insalate Di Matematica]

Dear all,

As part of the series of seminars "*Insalate di Matematica*", *Angelina
Zheng*, Postdoc researcher at the Università degli Studi Roma Tre, will
give a talk.
The speaker will deliver the talk *online* via Webex platform (see below
for more information) and the meeting will be *streamed also in room 3014*, at
the building U5-Ratio, Università degli Studi di Milano Bicocca.

Here the details:

*Date and time*: *30th of November 2022, 4:15 pm (CET)*

*Title*: "Stable cohomology of the moduli space of trigonal curve"

*Abstract*: The moduli space of algebraic curves is a central object in
algebraic geometry. The idea behind this space is that it answers to a
classification problem, by allowing us to classify algebraic curves up to
isomorphisms. Nonetheless, the geometry of this space is rather abstract
and subtle, and only few general statements are known. The aim of this talk
is to discuss some moduli spaces of genus g curves, such as trigonal
curves, from the point of view of one of the most important topological
invariants, their rational cohomology. In general, their full cohomology
ring is still unknown, but we have a complete description for some values
of g and we will provide a description for their stable cohomology ring.
This will be done by studying the natural embedding of trigonal curves in
Hirzebruch surfaces and by using Gorinov-Vassiliev's method for the
cohomology of complements of discriminants.

*Keywords*: Moduli space of curves - trigonal curves - rational cohomology
- Hirzebruch surface - Gorinov-Vassiliev's method - discriminants.
