We show how their heuristics can be generalized to Jacobians of curves of higher genus. We then elaborate this in genus 2 and study various related issues, such as the probability of cyclicity and the probability of primality of the number of points on the curve itself. Finally, we discuss the asymptotic behavior as the genus tends to infinity.", "revisions": [ { "version": "v2", "updated": "2011-09-30T15:38:54.000Z" } ], "analyses": { "subjects": [ "11N05", "11G10", "11G20" ], "keywords": [ "probability", "fixed finite prime field", "randomly chosen elliptic curve", "genus tends", "prime number" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1101.4792C" } } }
