This has an analytic counterpart in the approximation of symmetric positive definite Toeplitz matrices by submatrices of finite rank. We propose a notion of distance between them and prove a weak sense approximation result.", "revisions": [ { "version": "v1", "updated": "2020-09-12T10:08:04.000Z" } ], "analyses": { "keywords": [ "stationary processes", "toeplitz spectra", "symmetric positive definite toeplitz matrices", "weak sense approximation result", "analytic counterpart" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
