Some $q$-congruences involving central $q$-binomial coefficients

Number Theory 2021-10-22 v1

Abstract

Suppose that pp is an odd prime and mm is an integer not divisible by pp. Sun and Tauraso [Adv. in Appl. Math., 45(2010), 125--148] gave k=0n1(2kk+d)/mk\sum_{k=0}^{n-1}\binom{2k}{k+d}/m^k and k=0n1(2kk+d)/(kmk)\sum_{k=0}^{n-1}\binom{2k}{k+d}/(km^k) modulo pp for all d=0,1,nd=0,1, \ldots n and n=pan= p^a, where aa is a positive integer. In this paper, we present some qq-analogues of these congruences in the cases m=2,4m=2, 4 for any positive integer nn.
