The Hypercyclicity Criterion is a well-known sufficient condition for an operator to be hypercyclic. One open problem is whether there exists a space where the Hypercyclicity Criterion is also a necessary condition. For a number of reasons, the spaces with very-few operators are some natural candidates to be a positive answer to that problem. In this paper, we provide a theorem that establishes some relationships for operators in these spaces.", "revisions": [ { "version": "v1", "updated": "2020-02-05T02:51:09.000Z" } ], "analyses": { "keywords": [ "hypercyclic operators", "relationships", "hypercyclicity criterion", "well-known sufficient condition", "natural candidates" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
