Abstract
We prove a supercongruence modulo between the th Fourier coefficient of a weight 6 modular form and a truncated -hypergeometric series. Novel ingredients in the proof are the comparison of two rational approximations to to produce non-trivial harmonic sum identities and the reduction of the resulting congruences between harmonic sums via a congruence between the Apéry numbers and another Apéry-like sequence. We will highlight the role of computer algebra in this work, and give explicit examples indicating the need for algorithmic approaches to certifying .
This is joint work with Robert Osburn and Wadim Zudilin.
