On some hypergeometric supercongruence conjectures of Long

Abstract

Based on Ramanujan's theories of elliptic functions to alternative bases, commutative formal group laws, and supercongruence techniques, including the residue-sum technique, we provide an explicit "Hypergeometric-Modularity" method to obtain modularity results for certain hypergeometric Galois representations. We give a few applications. As a bi-product, we give a collection of eta quotients with multiplicative coefficients, explicit connections between hypergeometric values and periods of modular forms will be obtained.
