[Dottorcomp] Insalate di Matematica - L. Stefanello (10/03)

[Mbs Insalate Di Matematica]

Dear all,

as a part of the series of seminars *"Insalate di Matematica"*,
we remind you that today there is a seminar held by *Lorenzo
Stefanello* (Università
degli Studi di Pisa).
Moreover, we remind you that the talk will be held online and it will also
be broadcast in room 3014 (building U5-Ratio, Università degli Studi di
Milano-Bicocca) by prior reservation at the link
https://sites.google.com/view/insalate-di-matematica/reservation?authuser=0
You will be required to exhibit your green pass at the entrance of the
building.

Here the details:

*Speaker*: *Lorenzo Stefanello (**Università degli Studi di Pisa)*

*Date and time*: *10th March 2022, 2:00 pm (CET)*

*Title*: *"Hopf algebras, Galois modules, and skew braces**"*

*Webex link*:
https://unimib.webex.com/unimib/j.php?MTID=m1fe93efc8e4f946ea70f4846a24df073
 (*Password*: Insalate)

*Abstract*: In this talk, we deal with a quite recent and active area of
Mathematics connecting different theories by mean of apparently distant
topics: Hopf algebras (abstract algebra), Galois modules (number theory),
and skew braces (group theory). For each part we give the main definitions,
we overview the important results and connections with the other topics,
and we present open problems and directions.
At the end, we briefly discuss about a joint work with A. Caranti, where
some new constructions are introduced.

*Keywords*: Hopf algebras - Hopf–Galois extensions - Galois modules -
associated orders - skew braces - the Yang–Baxter equation.

*** We inform you that the talk will be recorded and uploaded on our
website. If you join the talk after the starting time, we kindly ask you to
ensure that your microphone and webcam are turned off ***

We are looking forward to seeing you!
