If the spectrum S survives when the matrix is rescaled by a factor of n, it can only be the eigenvalues of a Hilbert-Schmidt kernel k(x,y) on [0,1] x [0,1]. The rate function for k is $I(k)=1/2\\int h(k(x,y) dxdy$ where h is the Cramer rate function for the common distribution of the entries that is assumed to have a tail decaying faster than any Gaussian. The large deviation for S is then obtained by contraction.", "revisions": [ { "version": "v3", "updated": "2013-04-18T23:39:34.000Z" } ], "analyses": { "keywords": [ "random matrices", "large deviation result", "cramer rate function", "independent identically distributed entries", "tail decaying faster" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1106.4366C" } } }
