Underlying our analysis is the idea that the number of cycles of size k is roughly Poisson distributed with parameter 1/k. In particular, we establish strong results about the distribution of the number of cycles whose lengths lie in a fixed but arbitrary set I. Our techniques are motivated by the theory of sieves in number theory.", "revisions": [ { "version": "v1", "updated": "2021-04-24T20:34:42.000Z" } ], "analyses": { "keywords": [ "random permutation", "cycle type", "number theory", "arbitrary set", "lengths lie" ], "tags": [ "research tool" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
