This semigroup appeared in connection with the study of a characterization problem of mathematical statistics on $a$-adic solenoids containing an element of order 2. We answer the questions that arise in the study of arithmetic of the semigroup $\\Theta$. Namely, we describe the class of infinitely divisible distributions, the class of indecomposable distributions, and the class of distributions which have no indecomposable factors.", "revisions": [ { "version": "v1", "updated": "2023-12-14T03:38:06.000Z" } ], "analyses": { "subjects": [ "60B15" ], "keywords": [ "probability distributions", "arithmetic", "convolution semigroup", "real numbers", "characterization problem" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
