| Outline of Final Research Achievements |
We studied the one dimensional random Schroedinger operators with decaying facto, and with decaying coupling constant, in the order of -alpha at infinity, and our results are as follows.
(i) the level statistics are : Clock, Sine_{\beta}, and Poisson processes, depending on \alpha is bigger than, equal to, and less than 1/2, (ii) the asymptotic expansion of the number of eigenvalues on a given interval, which shows different behavior depending on the value of alpha, (iii) as a related question, the level statistics of the Gaussian beta ensemble at high temperature is Poisson.
