The result holds for orthogonal or unitarily invariant distributions of $Z$, in the cases when the linear eigenvalue statistic $\\operatorname{tr} f(Z)$ satisfies a CLT. The limit process interpolates between the fluctuations of individual matrix elements as $f(Z)_{1,1}$ and of the linear eigenvalue statistic. It can also be seen as a functional CLT for processes of randomly weighted measures.", "revisions": [ { "version": "v1", "updated": "2018-03-06T12:57:50.000Z" } ], "analyses": { "keywords": [ "functional clt", "random matrices", "partial traces", "linear eigenvalue statistic", "functional central limit theorem" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
