Some elementary observations on Narayana polynomials and related topics II: q-Narayana polynomials
Johann Cigler
We show that q-Catalan numbers, q- central binomial coefficients and q- Narayana polynomials are moments of q-analogues of Fibonacci and Lucas polynomials and related polynomials.

Elementary observations on Rogers-Szegö polynomials
Johann Cigler
The Rogers-Szegö polynomials are natural q-analogues of Newton binomials. In general they have no closed expression. We consider some exceptional cases which are products of a fact…
