Correlations between eigenvalues of large random matrices with independent entries.

چکیده
We derive the connected correlation functions for eigenvalues of large Her-mitian random matrices with independently distributed elements using both a diagrammatic and a renormalization group (RG) inspired approach. With the diagrammatic method we obtain a general form for the one, two and three-point connected Green function for this class of ensembles when matrix elements are identically distributed, and then discuss the derivation of higher order functions by the same approach. Using the RG approach we re-derive the one and two-point Green functions and show they are unchanged by choosing certain ensembles with non-identically distributed elements. Throughout, we compare the Green functions we obtain to those from the class of ensembles with unitary invariant distributions and discuss universality in both ensemble classes.

APPLICATION OF THE RANDOM MATRIX THEORY ON THE CROSS-CORRELATION OF STOCK PRICES
The analysis of cross-correlations is extensively applied for understanding of interconnections in stock markets. Variety of methods are used in order to search stock cross-correlations including the Random Matrix Theory (RMT), the Principal Component Analysis (PCA) and the Hierachical Structures. In this work, we analyze cross-crrelations between price fluctuations of 20 company stocks...
متن کاملA Law of Large Numbers for Finite-range Dependent Random Matrices
We consider random hermitian matrices in which distant abovediagonal entries are independent but nearby entries may be correlated. We find the limit of the empirical distribution of eigenvalues by combinatorial methods. We also prove that the limit has algebraic Stieltjes transform by an argument based on dimension theory of noetherian local rings.
متن کاملOn the Empirical Distribution of Eigenvalues of a Class of Large Dimensional Random Matrices
A stronger result on the limiting distribution of the eigenvalues of random Hermitian matrices of the form A+XTX∗, originally studied in Marčenko and Pastur [4], is presented. Here, X (N×n), T (n×n), and A (N×N) are independent, with X containing i.i.d. entries having finite second moments, T is diagonal with real (diagonal) entries, A is Hermitian, and n/N → c > 0 as N → ∞. Under addtional ass...
متن کاملOn the Spectrum of Sum and Product of Non-hermitian Random Matrices
In this note, we revisit the work of T. Tao and V. Vu on large non-hermitian random matrices with independent and identically distributed (i.i.d.) entries with mean zero and unit variance. We prove under weaker assumptions that the limit spectral distribution of sum and product of nonhermitian random matrices is universal. As a byproduct, we show that the generalized eigenvalues distribution of...
متن کاملEigenvalue variance bounds for Wigner and covariance random matrices
This work is concerned with finite range bounds on the variance of individual eigenvalues of Wigner random matrices, in the bulk and at the edge of the spectrum, as well as for some intermediate eigenvalues. Relying on the GUE example, which needs to be investigated first, the main bounds are extended to families of Hermitian Wigner matrices by means of the Tao and Vu Four Moment Theorem and re...
متن کاملUniversality of some models of random matrices and random processes
Many limit theorems in probability theory are universal in the sense that the limiting distribution of a sequence of random variables does not depend on the particular distribution of these random variables. This universality phenomenon motivates many theorems and conjectures in probability theory. For example the limiting distribution in the central limit theorem for the suitably normalized su...
