[Dottorcomp] Insalate di Matematica - B. Marchionna 11/1/2023

[Mbs Insalate Di Matematica]

Dear all,

As part of the series of seminars "Insalate di Matematica", *Bianca
Marchionna* (Universität Bielefeld & Università degli Studi di
Milano-Bicocca) 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*: 11th of January 2023, 5:00 pm (CET)

*Title*: "An introduction to zeta functions"

*Abstract*: A zeta function is a function in the complex variable [image: s]
defined by a Dirichlet series [image: \sum_{n=1}^{+\infty} a_n n^{-s}]. The
first example has been the Riemann zeta function, a kind of prototype for
the whole theory. More examples can be generated whenever the [image:
a_n]'s count
prescribed subobjects of a given structure (e.g., subgroups of index [image:
n] in a group, loops of length [image: n] in a graph ...).
The seminar aims at giving an overview on the world of zeta functions and
on some of the most common methods used wherein, with a particular emphasis
on Group Theory. After a brief introduction on Dirichlet series, the
discussion will vary from classical results to more recent developments and
works in progress.

*Keywords*: asymptotic algebra, Dirichlet series, group theory, zeta
functions

*Information to attend in room 2109*
The seminar will take place in room 2109, at the building U5-Ratio,
Università degli Studi di Milano Bicocca *(be careful with the change of
usual room)*.
