[hep-th] Seminar grupe za gravitaciju, cestice i polja, 16. decembar 2022

[Marija Dimitrijevic Ciric]

Zdravo svima,

evo najave mini-kursa koji ce, pocev od petka 16. decembra 2022. drzati 
Marko Vojinovic (Institut za fiziku)

Naslov:  Introduction to category theory and n-groups

Asptrakt: This is the first of a sequence of lectures about higher 
category theory and
n-groups. We will discuss the motivation for introducing n-groups, and
demonstrate some of their basic properties. After introducing the idea 
of
higher groups and discussing why they should be relevant for physics, we 
will
demonstrate the equivalence between a strict 2-group and a crossed 
module,
which is a technically more convenient tool. We will also discuss 
everything
on the example of the Poincaré 2-group, which should help us to build 
some
intuition.

The lecture is motivated mainly by papers arXiv:q-alg/9705009, 
arXiv:1003.4485.


Seminar pocinje u 11:15 uzivo na Fizickom fakultetu u sali 665, a moze
