[Dottorcomp] Insalate di Matematica - A. Cassella (21/03)

[Mbs Insalate Di Matematica]

 As part of the series of seminars *"Insalate di Matematica"*, *Alberto
Cassella*, PhD student at the Università degli Studi di Milano-Bicocca and
at the Universidad de Zaragoza, will deliver a talk.
According to the current Covid regulations, the seminar will be held
in a *hybrid
mode* *(more information below)*.

Here the details:

*Date and time*: *21th April 2022, 2:00 pm (CET)*

*Title*: *"**GGT tapas for lunch"*

*Abstract*: In the last decades Geometric Group Theory, namely the study of
infinite groups via geometric means, has spread out. Being at the
intersection among group theory, geometry, combinatorics and much more, it
has proved  to be a very fertile approach, allowing a deep understanding of
the properties of infinite groups. During this talk the basic ideas of
geometric group theory will be introduced, together with some of the most
common tools that can be used. Some of them will be introduced using
right-angled Artin groups (RAAGs) as an example. They are one of the most
important families of groups studied in geometric group theory and various
generalizations have been defined through the years. The last part of the
talk will introduce also one of such generalizations, namely twisted
right-angled Artin groups (TRAAGs). This last part is a joint work with S.
Blumer, I. Foniqi, C. Quadrelli and T. Weigel.

*Keywords*: Geometric group theory - RAAGs - Twisted RAAGS - Graphs -
CW-complexes - Classifying spaces - Group actions
