The unit tangent bundle $SM$ is foliated by the (weak) stable foliation $\\mathcal{W}^s$ of the geodesic flow. Let $\\Delta^s$ be the leafwise Laplacian for $\\mathcal{W}^s$ and let $\\overline{X}$ be the geodesic spray, i.e., the vector field that generates the geodesic flow. For each $\\lambda$, the operator $\\mathcal{L}_{\\lambda}:=\\Delta^s+\\lambda \\overline{X}$ generates a diffusion for $\\mathcal{W}^s$. We show that, as $\\lambda\\to -\\infty$, the unique stationary probability measure for the leafwise diffusion of $\\mathcal{L}_{\\lambda}$ converges to the normalized Lebesgue measure on $SM$.", "revisions": [ { "version": "v1", "updated": "2018-12-23T13:39:46.000Z" } ], "analyses": { "subjects": [ "37D40", "58J65" ], "keywords": [ "stable diffusions", "unique stationary probability measure", "geodesic flow", "unit tangent bundle", "normalized lebesgue measure" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
