Outline of Final Research Achievements

I obtained several results concerning the representation theory of quantum groups at roots of 1. The most important aim was to establish the Beilinson-Bernstein type correspondence for quantum groups at roots of 1. The problem is not yet solved in its full generality, but I have established it for the quantum groups of type A. This is a big progress. In connection with the quantum groups at even roots of 1, I also considered the quantum groups at q=-1 and proved that it is isomorphic to the enveloping algebra of a Lie multi-super algebra. I investigated also the quantized coordinate algebras and affine Hecke algebras, but obtained no remarkable results on them.
