[phys4phys] Group for Gravitation, Particle and Fields seminar, Friday 24 February 2023

[Marija Dimitrijevic Ciric]

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 24 February 2023 at 
11:00 at the Faculty of Physics, lecture hall 665.


The talk entitled

Introduction to category theory and n-groups (part 6)

is the sixth in the series of seminars on n-groups and categories and 
will be given by Marko Vojinovic (Institute of Physics Belgrade).

Abstract: In the final lecture of the series, we will present a theorem 
relating a 2-group, a path 2-groupoid, a 2-connection and a principal 
2-bundle. This theorem generalizes some concepts of differential 
geometry, specifically the notion of parallel transport and holonomy, by 
introducing the so-called surface parallel transport and surface 
holonomy. Such a generalization represents a new tool to build gauge 
theories in physics, and has direct applications for the constructions 
of models of quantum gravity.

The lectures are based on material from papers arXiv:q-alg/9705009 and 
arXiv:1003.4485.
