Description of the Project

The research project focuses on representation theory, with an emphasis on the study of Lie algebras, W-algebras, quantum groups and their connections to various areas of mathematics and mathematical physics. It spans topics ranging from vertex algebras and Poisson vertex algebras to Yangians and infinite dimensional Lie algebras, from Drinfeld-Jimbo quantum groups to Yangians and affine and toroidal quantum algebras, focusing on their interplay with the theory of integrable systems. A main goal of the project is the construction of fundamental operators, such as R-matrices and K-matrices, and the discovery of new relations between W-algebras and twisted Yangians.
