摘要

Various q-congruences related to Carlitz’s formula have been recently studied by many authors. We establish a unified form of these q-congruences, which includes all of the known q-congruences motivated by Carlitz’s formula as special cases. Apart from Carlitz’s formula and a q-analogue of Morley’s congruence, important ingredients in our proof of the unified form include a q-analogue of Granville’s congruence and a recurrence formula for a summation. As an application, we prove a q-congruence conjectured by Tauraso.
