Super congruences concerning binomial coefficients and Apéry-like numbers

preprint2020arXivOpen access

Abstract

Let pp be a prime with p>3p>3, and let a,ba,b be two rational p−p-integers. In this paper we present general congruences for ∑k=0p−1(ak)(−1−ak)pk+b(modp2)\sum_{k=0}^{p-1}\binom ak\binom{-1-a}k\frac p{k+b}\pmod {p^2}. For n=0,1,2,…n=0,1,2,\ldots let DnD_n and bnb_n be Domb and Almkvist-Zudilin numbers, respectively. We also establish congruences for ∑n=0p−1Dn16n,∑n=0p−1Dn4n,∑n=0p−1bn(−3)n,∑n=0p−1bn(−27)n(modp2)\sum_{n=0}^{p-1}\frac{D_n}{16^n},\quad \sum_{n=0}^{p-1}\frac{D_n}{4^n}, \quad \sum_{n=0}^{p-1}\frac{b_n}{(-3)^n},\quad \sum_{n=0}^{p-1}\frac{b_n}{(-27)^n}\pmod {p^2} in terms of certain binary quadratic forms.
