高斯矩阵对随机正交矩阵的全变差逼近

Total variation approximation of random orthogonal matrices by Gaussian matrices

Kathryn Stewart

摘要:

本文研究按Haar测度分布的随机正交矩阵的渐近分布。我们研究了$W_n$、Haar分布矩阵左上方的$p_n \times q_n$和$p_nq_n$独立标准高斯随机变量的联合分布之间的全变差距离。我们证明了当$p_nq_n = o(n)$时,全变差距离收敛到零.

英文摘要:

The topic of this paper is the asymptotic distribution of random orthogonal matrices distributed according to Haar measure. We examine the total variation distance between the joint distribution of the entries of $W_n$, the $p_n \times q_n$ upper-left block of a Haar-distributed matrix, and that of $p_nq_n$ independent standard Gaussian random variables. We show that the total variation distance converges to zero when $p_nq_n = o(n)$.
