The aimed transformation preserves a foliation which is almost everywhere uniformly contracted with possible discontinuity sets, which are parallel to the contracting direction. We apply the spectral gap property and the $\\zeta$-H\\\"older regularity of the disintegration of its equilibrium state to prove a quantitative statistical stability statement. More precisely, under deterministic perturbations of the system of size $\\delta$, we show that the physical measure varies continuously with respect to a strong $L^\\infty$-like norm. Moreover, we prove that its modulus of continuity is $O(\\delta^\\zeta \\log \\delta)$.", "revisions": [ { "version": "v1", "updated": "2020-08-13T04:01:08.000Z" } ], "analyses": { "subjects": [ "37A25", "37A10", "37C30", "37D50" ], "keywords": [ "piecewise partially hyperbolic maps", "quantitative statistical stability", "equilibrium state", "partially hyperbolic dynamics", "spectral gap property" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
