Summary: This paper has double scope. In the first part we study the limiting empirical spectral distribution of a \(n \times n\) symmetric matrix with dependent entries. For a class of generalized martingales we show that the asymptotic behavior of the empirical spectral distribution depends only on the covariance structure. Applications are given to strongly mixing random fields. The technique is based on a blend of blocking procedure, martingale techniques and multivariate Lindeberg’s method. This means that, for this class, the study of the limiting spectral distribution is reduced to the Gaussian case. The second part of the paper contains a survey of several old and new asymptotic results for the empirical spectral distribution for Gaussian processes, which can be combined with our universality results.
