The result is proved by developing a suitable perturbation theory that exploits the natural pairing between resonant and co-resonant differential forms. To obtain a metric conformal perturbation we need to establish the non-vanishing of the pushforward of a certain product of resonant and co-resonant states and we achieve this by a suitable regularisation argument. Along the way we describe geometrically all resonant differential forms (at zero) for a closed hyperbolic 3-manifold and study the semisimplicity of the Lie derivative.", "revisions": [ { "version": "v1", "updated": "2020-09-17T23:30:08.000Z" } ], "analyses": { "keywords": [ "ruelle zeta function", "generic conformal metric perturbation", "metric conformal perturbation", "co-resonant differential forms", "hyperbolic case" ], "note": { "typesetting": "TeX", "pages": 69, "language": "en", "license": "arXiv", "status": "editable" } } }
