As a candidate starting configuration for this problem, Armentano, Beltr\\'an and Shub considered the set of points given by the stereographic projection of the roots of the random elliptic polynomial of degree $n$ and computed the expected logarithmic energy. We study the fluctuations of the logarithmic energy associated to this random configuration and prove a central limit theorem. Our approach shows that all cumulants of the logarithmic energy are asymptotically linear in $n$, and hence the energy is well-concentrated on the scale of $\\sqrt{n}$.", "revisions": [ { "version": "v1", "updated": "2023-04-06T07:11:10.000Z" } ], "analyses": { "keywords": [ "random polynomials", "fluctuations", "smales seventh problem asks", "random elliptic polynomial", "central limit theorem" ], "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable" } } }
