Various corrections and referee suggestions incorporated", "categories": [ "math.PR" ], "abstract": "The famous \\emph{circular law} asserts that if $M_n$ is an $n \\times n$ matrix with iid complex entries of mean zero and unit variance, then the empirical spectral distribution (ESD) of the normalized matrix $\\frac{1}{\\sqrt{n}} M_n$ converges almost surely to the uniform distribution on the unit disk $\\{z \\in \\C: |z| \\leq 1 \\}$. After a long sequence of partial results that verified this law under additional assumptions on the distribution of the entries, the full circular law was recently established in \\cite{TVcir2}. In this survey we describe some of the key ingredients used in the establishment of the circular law, in particular recent advances in understanding the Littlewood-Offord problem and its inverse.", "revisions": [ { "version": "v3", "updated": "2009-01-01T17:05:12.000Z" } ], "analyses": { "subjects": [ "15A52", "60G50" ], "keywords": [ "spectral distribution", "littlewood-offord problem", "random matrices", "universality", "full circular law" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0810.2994T" } } }
