$q$-Supercongruences with parameters

Abstract

In terms of the creative microscoping method recently introduced by Guo and Zudilin [Adv. Math. 346 (2019), 329--358], we find a qq-supercongruence with four parameters modulo Φn(q)(1aqn)(aqn)\Phi_n(q)(1-aq^n)(a-q^n), where Φn(q)\Phi_n(q) denotes the nn-th cyclotomic polynomial in qq. Then we empoly it and the Chinese remainder theorem for coprime polynomials to derive a qq-supercongruence with two parameters modulo [n]Φn(q)3[n]\Phi_n(q)^3, where [n]=(1qn)/(1q)[n]=(1-q^n)/(1-q) is the qq-integer.
