We study their structure showing that the local invertibility of a restriction is independent of its singularity set. We also study the spectral theory of the transfer operators of a probability preserving inner functions, establishing a spectral gap and some central limit properties of stochastic processes driven by them as a consequence of suitable analytic perturbations of the transfer operators.", "revisions": [ { "version": "v1", "updated": "2023-05-24T16:03:21.000Z" } ], "analyses": { "subjects": [ "30J05", "37C30", "60F05", "28A50" ], "keywords": [ "transfer operators", "stochastic processes driven", "central limit properties", "probability preserving inner functions", "suitable analytic perturbations" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable" } } }
