These results have applications both to ergodic theory and to Diophantine approximation. Namely, earlier results of Dani (finiteness of locally finite ergodic unipotent-invariant measures on real homogeneous spaces) and Kleinbock-Margulis (strong extremality of nondegenerate submanifolds of $\\Bbb R^n$) are generalized to the $S$-arithmetic setting.", "revisions": [ { "version": "v1", "updated": "2005-06-24T19:11:58.000Z" } ], "analyses": { "subjects": [ "11J83", "37A13" ], "keywords": [ "metric diophantine approximation", "arithmetic homogeneous spaces", "applications", "locally finite ergodic unipotent-invariant measures", "adic lie groups" ], "note": { "typesetting": "TeX", "pages": 56, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......6510K" } } }
