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.

Nonlinear analysis of geometric variational problems
We investigate variational problems arising in nature and clarify their underlying principles through mathematical abstraction.
