Title: " Stability estimates in some classical functional inequalities. "
Speaker: Jean Dolbeaut (Université Paris Dauphine - PSL)
Abstract:
In some classical functional inequalities, optimal functions and optimal constants are known.
The next question is to understand which distance to the set of the optimal functions is controlled by the deficit,
that is, the difference of the two sides of the inequality written with the optimal constant. In 1991, an answer was
given by Bianchi and Egnell in the case of a Sobolev inequality on the Euclidean space, using compactness methods.
A major issue with the method is that the new constant is so far unknown. The purpose of this lecture is to review
some examples of related functional inequalities in which one can at least give an estimate of the stability constant.

Title: " Integrable triples in simple Lie algebras "
Speaker: Daniele VALERI ( “Sapienza” Università di Roma )
Abstract:
We define integrable triples in simple Lie algebras and classify them, up to equivalence.
The classification is used to show that all (but few exceptions) classical affine W-algebras W(g , f ),
where g is a simple Lie algebra and f a nilpotent element, admit an integrable hierarchy of bi-Hamiltonian PDEs.
This integrable hierarchy generalizes the Drinfeld-Sokolov hierarchy which is obtained when f is the sum of negative
simple root vectors.

Title: " Higher-order theory for highest weight modules: positive weight-formulas, and resolutions and characters for higher order Verma modules"
Speaker: Apoorva KHARE (Indian Institute of Science)
Abstract:
We introduce higher order Verma modules over a Kac-Moody algebra g (one may assume this to be sln throughout the talk, without sacrificing novelty).
Using these, we present positive formulas (without cancellations) for the weights of arbitrary highest weight g-modules V. The key ingredient is that
of "higher order holes" in the weights, which we introduce and explain.
