| Gauge Theories: a scientific success story and still a contemporary challenge |
| Speaker: | Prof. Thomas Strobl (Univ. Lyon) |
| Abstract: | We review the basic idea of gauging, including the transition from Maxwell
to Yang-Mills theory. This transition is marked by the corresponding one
from abelian to non-abelian Lie groups. The introduction of this then-new theory
by Yang and Mills in 1954 was crowned on the physics side by a Nobel prize in
1979 (and related ones in 1999 and 2013).
In the main part of the talk, we propose to go one step further, replacing the notion
of a Lie group by the one of a Lie groupoid. While by now we are already sufficiently
used to the notion of Lie groups in physics, the transition from abelian to non-abelian
groups is mathematically probably more profound than the one from groups to groupoids.
We present a mathematical framework that generalizes Yang-Mills theories to structural
Lie groupoids. To find a physically relevant application of this is a challenge for the
coming generations |
