On supersingular elliptic curves and hypergeometric functions

Keenan Monks

Vol. 5 (2012), No. 1, 99–113
Abstract

The Legendre family of elliptic curves has the remarkable property that both its periods and its supersingular locus have descriptions in terms of the hypergeometric function 2F1(12 12 1 |z). In this work we study elliptic curves and elliptic integrals with respect to the hypergeometric functions 2F1(13 23 1 |z) and 2F1(12 512 1 |z), and prove that the supersingular λ-invariant locus of certain families of elliptic curves are given by these functions.
