Eigenvalue distribution of large random matrices with correlated entries
A. Khorunzhii Mathematical Division, B. Verkin Institute for Low Temperature Physics and Engineering, National Academy of Sciences of Ukraine, 47, Lenin Ave., 310164, Kharkov, Ukraine
Abstract:
We study the normalized eigenvalue counting function $N_n(\lambda)$ of an ensemble of $n\times n$ symmetric random matrices with statistically dependent arbitrary distributed entries $u_n(x,y)$, $x,y=1,\dots,n$. We prove that if the correlation function $S$ of the entries is the same for each $n$ and the correlation coefficient of random fields $\{u_n(x,y)\}$ decays fast enough, then in the limit $n\to\infty$ the measure $N_n(d\lambda)$ weakly converges in probability to a nonrandom measure $N(d\lambda)$. We derive an equation for the Stieltjes transform of limiting $N_n(d\lambda)$ and show that the latter depends only on the limiting matrix of averages of $u_n(x,y)$ and the correlation function $S$.
