Supercongruences involving Domb numbers and binary quadratic forms

Number Theory 2021-12-24 v1

Abstract

In this paper, we prove two recently conjectured supercongruences (modulo p3p^3, where pp is any prime greater than 33) of Zhi-Hong Sun on truncated sums involving the Domb numbers. Our proofs involve a number of ingredients such as congruences involving specialized Bernoulli polynomials, harmonic numbers, binomial coefficients, and hypergeometric summations and transformations.
