Specifically, we express these polynomials as the inverse Fourier transform of a Hankel determinant that satisfies a Painlev\\'e V equation. We prove that $\\gamma_k(c)$ is very smooth at its transition points, and also determine the asymptotics of $\\gamma_k(c)$ in a large neighbourhood of $k=c/2$. Finally, we consider the coefficients that appear in the asymptotics of elliptic Aliquot cycles.", "revisions": [ { "version": "v1", "updated": "2018-05-22T18:41:44.000Z" } ], "analyses": { "subjects": [ "11M06", "33E17" ], "keywords": [ "number theory", "multidimensional integrals", "connections", "study piecewise polynomial functions", "inverse fourier transform" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
