The paper deals with the question about the behavior of the concentration function of the random variable $\\sum_{k=1}^{n}a_k X_k$ according to the arithmetic structure of coefficients $a_k$. Recently the interest to this question has increased significantly due to the study of distributions of eigenvalues of random matrices. In this paper we formulate and prove some refinements of the results of Friedland and Sodin (2007) and Rudelson and Vershynin (2009).", "revisions": [ { "version": "v1", "updated": "2012-03-25T17:13:37.000Z" } ], "analyses": { "subjects": [ "60F05", "60G50" ], "keywords": [ "independent random variables", "concentration function", "weighted sums", "independent identically distributed random variables", "paper deals" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1203.5520E" } } }
