Some $q$-congruences involving central $q$-binomial coefficients (2110.10361v1)

Published 20 Oct 2021 in math.NT

Abstract: Suppose that $p$ is an odd prime and $m$ is an integer not divisible by $p$. Sun and Tauraso [Adv. in Appl. Math., 45(2010), 125--148] gave $\sum_{k=0}{n-1}\binom{2k}{k+d}/mk$ and $\sum_{k=0}{n-1}\binom{2k}{k+d}/(kmk)$ modulo $p$ for all $d=0,1, \ldots n$ and $n= pa$, where $a$ is a positive integer. In this paper, we present some $q$-analogues of these congruences in the cases $m=2, 4$ for any positive integer $n$.
