Some $q$-congruences with parameters

Streszczenie
Let $\varPhi_n(q)$ be the $n$th cyclotomic polynomial in $q$. Recently, the author and Zudilin devised a method, called ‘creative microscoping’, to prove some $q$-supercongruences mainly modulo $\varPhi_n(q)^3$ by introducing an additional parameter $a$. In this paper, we use this method to confirm some conjectures on $q$-supercongruences modulo $\varPhi_n(q)^2$. We also give some parameter-generalizations of known $q$-supercongruences. For instance, we present further generalizations of a $q$-analogue of a famous supercongruence of Rodriguez-Villegas:
