Recently the first author proved a congruence proposed in 2006 by Adamchuk: k=12p/32k k 0(modp2) for any prime p = 1(mod 3). In this paper, we provide more examples (with proofs) of congruences of the same kind k=1ap/r2k k xk(modp2) where p is a prime such that p 1(modr), a/r is a fraction in (1/2, 1) and x is a p-adic integer. The key ingredients are the p-adic Gamma function Γp and a special class of computer-discovered hypergeometric identities.

三对关于中心二项式系数之和的同余

最近,第一作者证明了 Adamchuk 在 2006 年提出的一致性:ķ=12p/32ķ ķ 0(模组p2)对于任何素数p = 1(模组 3). 在本文中,我们提供了更多同类同余的示例(带证明)ķ=1一种p/r2ķ ķ Xķ(模组p2)在哪里p是一个素数,使得p 1(模组r),一种/r是分数(1/2, 1)X是一个p-adic 整数。关键成分是p-adic Gamma 函数Γp和一类特殊的计算机发现的超几何恒等式。
