Compact support probability distributions in random matrix theory

We consider a generalization of the fixed and bounded trace ensembles introduced by Bronk and Rosenzweig up to an arbitrary polynomial potential. In the large-n limit we prove that the two are equivalent and that their eigenvalue distribution coincides with that of the ”canonical” ensemble with measure exp[-nTr V(M)]. The mapping of the corresponding phase boundaries is illuminated in an explicit example. In the case of a Gaussian potential we are able to derive exact expressions for the oneand two-point correlator for finite n, having finite support. CPT-98/P.3675 cond-mat/9809270
