| Outline of Final Research Achievements |
In this study, some results are obtained by using the orthogonality of group or algebra characters. First result is related to stochastic models called Poker-dice game and Ehrenfest's urn model. Their ergodic properties and cut-off phenomenons are analyzed by using representation theoretical method. Second result is a formula on certain algebraic relations of Schur functions. Some formulas are proved by the representation of an affine Lie algebra and the theory of the symmetric functions. Furthermore the representation theoretic meaning of these formulas is revealed. The last result is a combinatorial formula of (class) regular partitions. The relation between the product of all parts of the class regular partitions and that of multiplicities are given.
