| Outline of Final Research Achievements |
We completely determined the structure of the center of a quantized enveloping algebra at an odd root of unity. This gives the variety consisting of central characters. In order to develop the representation theory we need more information about the Poisson structure of this variety. We have almost accomplished it although there remain some points to be checked. We also investigated the representation theory of quantized coordinate algebras. In particular, we have given a description of the Soibelman module via generators and relations. Using this we gave a unified proof of a result of Kuniba-Okado-Yamada. Moreover, we gave a proof of their conjecture. We investigated the Drinfeld pairing of the quantized enveloping algebra by algebraic methods. We gave a new simpler proof of the fact that the Drinfeld pairing is invariant under the action of the braid group.
