 Research Activities

My research areas are: representation theory of quantum groups; elliptic Roperators; and dynamical YangBaxter maps. The dynamical YangBaxter map is a solution to the quantum YangBaxter equation on a suitable tensor category. This concept induces bialgebroids and tensor categories of their dynamical representations. My interest is to clarify relations between them and to construct Hopf algebroids by means of the dynamical YangBaxter maps.
