We compute point spectrum and eigenfunctions for a class of truncated Toeplitz operators with polynomial analytic and antianalytic parts. We show that, for a class of model spaces, truncated Toeplitz operators with symbols of the form $\\Phi(z) =a \\bar{z} +b + cz$, $|a| \\ne |c|$, have complete sets of eigenvectors, and, in particular, are not hypercyclic.", "revisions": [ { "version": "v2", "updated": "2022-12-06T23:33:01.000Z" } ], "analyses": { "subjects": [ "47A16", "47B35", "30H10" ], "keywords": [ "truncated toeplitz operator", "point spectrum", "hypercyclicity problem", "model space", "open problem" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable" } } }
