[Insalate Di Matematica]

Dear all,

As part of the series of seminars "Insalate di Matematica", *Simone
Pesatori* (Università degli Studi Roma Tre) will give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: *22th of March 2023, 5:00 pm (CET)*

*Title*: "Coincident root loci and the moduli space of rational elliptic
surfaces"

*Abstract*: Elliptic fibrations are strongly characterized by their
singular fibers. We analyze the moduli spaces of elliptic surfaces over the
projective line [image: \mathbb{P}^1] and construct a stratification of
these spaces in terms of the singular fibers that the surfaces have.
In order to do that we need to investigate a very natural problem. Let [image:
\mathbb{P}^d] be the space parametrizing homogeneous degree d polynomials
in two variables: what happens if the roots of the polynomials collapse?
Given a partition [image: \sigma] of [image: d], how is the locus in [image:
\mathbb{P}^d] corresponding to polynomials having roots with the
multiplicities prescribed by [image: \sigma]?

*Keywords*: algebraic geometry, elliptic fibrations, singular fibers,
moduli spaces.

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca.

*Information to attend online *
