摘要:
Let M be a randomly chosen n x n permutation matrix. For a fixed are of the unit circle, let X be the number of eigenvalues of M which lie in the specified are. We calculate the large n asymptotics for the mean and variance of X, and show that (X - E[X])/(Var(X))(1/2) is asymptotically normally distributed. In addition, we show that for several fixed arcs I-1,...,I-m, the corresponding random variables are jointly normal in the large n limit.
