| Research Abstract |
Quantum chaos or the classical-semiiclassical-quantum correspondence is one of the main topics around the problem of the chaos of dynamical systems. The purpose of the research was to investigate the mathematical problems in the following three directions.
1) Discrete analogue and 2) Trace formulas. One of the implications carried by the concept of Li-Yorke's chaos is clarified by Y.Takahashi (with Y.Baba and I.Kubo). T.Shirai obtained a remarkable result : a graph version of Gutzwiller's formula does hold exactly.
3) Hydrodynamical limit of many particle systems and analysis of the limit equations. There are several results in this direction. K.Ohkitani computed Lyapunov exponents for the developped turbulence (with Yamada), H.Okamoto and Sakajo studied the roll-up phenomenon of vortex sheet, K.Murota discussed the bifurcation of soil shear. Also, the exact theory of singular perturbation due to H.Kawai and Y.Takei is suggesive in this direction. Y.Takahashi organized a meeting on asymptotic theory in stochastic analysis, including lectures concerning the recent development of oscillatory integral theory. He also gave a new simpler proof to the result of 16 years ago (with K.Hara) and tried to describe the results in random matrix theory from the view-point of point process and its scaling limit (partially, announced at Oberwolfach institute). Also, he started the stochastic-analytical study of the quadratic form associated with the Cauch singular integral inspired by a result of Johansson (1995) extending Szego's result in finite dimension (with T.Chiyonobu).
