Outline of Final Research Achievements |
We have developed Weingarten calculus, which is a method for computing mixed moments of matrix elements from various random matrices. Specifically, we construct Weingarten calculus for random matrices associated with seven kinds of compact symmetric spaces, inverses of compound Wishart matrices, and pseudo-inverses of Ginibre matrices. Furthermore, we obtain a new inequality for traces from circular beta-ensembles by using Jack polynomials, and show the central limit theorem as its application. Also, we find a polynomiality of Plancherel averages.
