[Insalate Di Matematica]

Dear all,

For the *next appointment* of the series of seminars "Insalate di
Matematica", *Alessandro Proserpio* (University of Glasgow) 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*: *2nd of April 2025, 4:30 pm (CEST)*

*Title*: "Permutations of polynomial roots and flat coordinates of
Frobenius manifolds"

*Abstract*: A complex polynomial of given degree is completely specified by
either its roots or its coefficients. Relations between the two are
famously given by Viéta identities. Within the theory of Frobenius
manifolds, these serve as a transition function between two distinguished
coordinate systems. We discuss how this can be generalised to rational
functions. In particular, it turns out that the Frobenius manifold
structure on the space of some rational functions can
be described from a suitable polynomial one, the additional information
being encoded into
polynomial invariants under the diagonal action of the symmetric group.
This is based on a
joint work with Ian Strachan.

*Keywords:* Frobenius manifolds, Landau-Ginzburg superpotentials, symmetric
groups

*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.
