These problems turn out to be closely connected and even, in a sense, equivalent. The new approach based on the factorizations allows us to answer a number of challenging questions about truncated Toeplitz operators posed by Donald Sarason.", "revisions": [ { "version": "v1", "updated": "2010-09-26T20:11:04.000Z" } ], "analyses": { "subjects": [ "47B35", "47B32" ], "keywords": [ "truncated toeplitz operators", "coinvariant subspaces", "carleson-type embedding theorems", "donald sarason", "backward shift operator" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1009.5123B" } } }
