A family of q-supercongruences from Watson’s
transformation
摘要
We prove a family of q-supercongruences modulo the fourth power of a cyclotomic polynomial. Our results may be regarded as a uniform generalization of a q-supercongruence by Wei, two q-supercongruences by Liu and Wang, and two previous q-supercongruences by the author himself. Our proof makes use of the method of “creative microscoping” introduced by the author and Zudilin, Watson’s
