| Outline of Final Research Achievements |
We quantize the tau-functions generated by the birational action of the Weyl group associated to any symmetrizable generalized Cartan matix (GCM). For example, if the GCM is of the affine A_2 type, then the quantized tau-functions are identified with the ones for the quantum Painleve IV equation. The classical tau-functions are polynomials in independent variables. We establish the quantized version that the quantized tau-functions are non-commutative polynomials in the quantized independent variables. The proof is derived from the certain formulae of the translation functors in the BGG category for the Kac-Moody algebra. Using the theory of quantum groups, we can generalize these results to the cases of q-difference analogues.
