Hi everybody,
This *Friday 21st at 11:30 in Aula C* we will keep on going with the
Cordas-Club. In this occasion the discussion will be led by *Sibylle
Driezen* who will talk to us about the paper* "Integrable E-models, 4d
Chern-Simons theory and Affine Gaudin Models" *by Sylvain Lacroix and
Benoit Vicedo. .
*Abstract:*
These researchers belong to a group of people that try to describe
2-dimensional integrable field theories in a general and rigorous way.
Recently they have been employing the framework of 4d Chern Simons (CS)
theory, proposed by Costello and Yamazaki (https://arxiv.org/abs/1908.02289)
in order to do so. In this paper they show that in a very general set-up,
the 2d reduced theories from 4d CS are naturally captured by integrable
E-models. This is quite interesting because the latter have been introduced
by Klimcik and Severa ('95 -- '97) to make Poisson-Lie T-duality of sigma
model manifest, which is a more general notion of conventional T-duality.
This paper therefore adds another interesting connection between
integrability and generalised dualities. After motivating several of these
concepts, and perhaps illustrate some with a simple example, I will sketch
their methods and results briefly in view of time.
