We present an elementary proof of the fact that $$(\\Vol K)(\\Vol K\\dual)\\ge \\frac{b_n^2}{(\\log_2 n)^n},$$ where $b_n$ is the volume of the Euclidean ball of radius 1. The inequality is asymptotically weaker than the estimate of Bourgain and Milman, which replaces the $\\log_2 n$ by a constant. However, there is no known elementary proof of the Bourgain-Milman theorem.", "revisions": [ { "version": "v1", "updated": "1992-11-01T00:00:00.000Z" } ], "analyses": { "keywords": [ "convex geometry", "low-technology estimate", "elementary proof", "dimensional symmetric convex body", "bourgain-milman theorem" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1992math.....11216K" } } }
