Specifically, the random variables are replaced with elements in some measure space $(\\Lambda; dx)$, the resultant real-valued functions on $\\Lambda^N$ being called generalized $N$-means. It is shown that a.e. convergence of sequences, measurability, essential boundedness and, under certain conditions, integrability with respect to probability measures of generalized $N$-means and their kernels are equivalent. These results are crucial for the solution of the inverse problem in classical statistical mechanics in the canonical formulation.", "revisions": [ { "version": "v1", "updated": "2015-07-14T04:59:06.000Z" } ], "analyses": { "subjects": [ "28A20", "28A25", "28A35", "62H12", "82B21" ], "keywords": [ "measure-theoretic properties", "statistical physics", "u-statistics", "inverse problem", "probability measures" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150703721N" } } }
