q-Riordan array for q-Pascal matrix and its inverse matrix

Abstract

In this paper, we prove the q-analogue of the fundamental theorem of Riordan arrays. In particular, by defining two new binary operations *(q) and *(1/q), we obtain a q-analogue of the Riordan representation of the q-Pascal matrix. In addition, by aid of the q-Lagrange expansion formula we get q-Riordan representation for its inverse matrix.
