Outline of Final Research Achievements |
We study several aspects of integrable systems and symmetric functions, toward unraveling combinatorial structure of special polynomials associated to certain solutions of the Painleve-type equations. 1. We find Giambelli-type determinant identities, which characterize the expansion coefficients of the \tau-function of the KP hierarchy, and give new determinant expressions for Schur functions. 2. We find a relation between two generalizations of Schur Q-functions corresponding to rational Schur functions. Also we give several identities and positivity conjectures for Schur Q-functions associated to the root system of type C.
