The proof is based on ratio asymptotics for these polynomials. We can apply this result to three examples of multiple orthogonal polynomials, in particular Jacobi-Pineiro, Laguerre I and the example associated with Macdonald functions. We also discuss an application to Toeplitz matrices.", "revisions": [ { "version": "v1", "updated": "2006-06-19T09:50:01.000Z" } ], "analyses": { "subjects": [ "33C45", "42C05", "15A18" ], "keywords": [ "asymptotic zero distribution", "multiple orthogonal polynomials", "four-term recurrence relation", "varying recurrence coefficients", "ratio asymptotics" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......6440C" } } }
