Understanding identities through representations
Our aim is to understand identities through representations of quantum groups, by means of crystal bases; one of the main tools for the study of representations of quantum groups.
Representation theory of infinite-dimensional Lie algebras
We study lifestyle changes occurring in the 21st century and the use of information and communication technology for the realization of a knowledge-based society.
