Consider a Lipschitz map $T: X \\rightarrow \\Rn$, with Lipschitz constant $\\leq 1$. Then one can ask whether the image $TX$ can have large projections on many directions. For a large class of spaces $X$, we show that there are directions $\\phi \\in \\nsphere$ on which the projection of the image $TX$ is small on the average, with bounds depending on the dimension $n$ and the eigenvalues of the Laplacian on $X$.", "revisions": [ { "version": "v1", "updated": "2011-06-24T08:52:55.000Z" } ], "analyses": { "keywords": [ "metric space", "probability measure", "large class", "lipschitz map", "directions" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1106.4910K" } } }
