We investigate the eigenvalues of $P(Y,A)$ outside the spectrum of $P(c,a)$ where $c$ is a circular system which is free from $a$. We provide a sufficient condition to guarantee that these eigenvalues coincide asymptotically with those of $P(0,A)$.", "revisions": [ { "version": "v1", "updated": "2019-06-25T17:24:47.000Z" } ], "analyses": { "keywords": [ "deterministic matrices", "outlier eigenvalues", "non-hermitian polynomials", "square random matrix", "eigenvalues coincide" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
