Some q -Supercongruences Modulo the Fifth Power of a Cyclotomic Polynomial from Squares of q -Hypergeometric Series

In this paper, in view of the transformation formulae for q -hypergeometric series, a lemma of El Bachraoui, the creative microscoping method developed by Guo and Zudilin and the Chinese remainder theorem for coprime polynomials, we obtain certain q -supercongruences modulo the fifth power of a cyclotomic polynomial from squares of q -hypergeometric series.
