Abstract

A q-analogue of second kind r-Whitney numbers, denoted by ������,��[��,��], is defined by means of a triangular recurrence relation. The rational generating function is obtained which, consequently, gives an explicit formula in symmetric function form. This explicit formula is used to give combinatorial interpretation for ������,��[��,��] in the context of 0-1 tableau. A kind of generalization of Carlitz formula is derived using the combinatorics of A-tableaux. Moreover, some convolution-type identities for ������,��[��,��] are established which yield LU-factorization of the matrices (������,��[��,��])��,��≥0.
