An explicit formula of powers of the $2\times 2$ quantum matrices and its applications

Abstract

We present an explicit formula of the powers for the $2\times 2$ quantum matrices, that is a natural quantum analogue of the powers of the usual $2\times 2$ matrices. As applications, we give some non-commutative relations of the entries of the powers for the $2\times 2$ quantum matrices, which is a simple proof of the results of Vokos-Zumino-Wess (1990).
