This article contains a survey of the known properties of bubbles, as well as a variety of open questions. In particular, we show that bubbles can intersect and self-intersect, and provide approximate pictures of bubbles for perturbations of M\\\"obius circle diffeomorphisms.", "revisions": [ { "version": "v1", "updated": "2017-08-03T09:39:41.000Z" } ], "analyses": { "subjects": [ "37E10", "37E45" ], "keywords": [ "complex rotation numbers", "intersections", "circle diffeomorphism", "complex analogue", "approximate pictures" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
