This paper discusses some algebraic properties of Parikh q-matrices. A new way of q-counting of the subwords of a given word w is introduced. It has been shown that the notion of alternating Parikh q-matrices can be characterized using the q-counting polynomials. We also show that a Minor of a Parikh q-matrix is a polynomial in q with non-negative coefficients. Further this work provides an extension of the definition of partial sum to Parikh q-matrices. A characterization on words x and y such that the partial sum of their Parikh q-matrices is always a Parikh q-matrix is also given. We also provide some partial results for the case q = 1. © 2016 World Scientific Publishing Company.
