摘要:
In this paper, a generalization of Askey-Wilson polynomials is introduced. These polynomials are obtained from the Askey-Wilson polynomials via the addition of two mass points to the weight function of them at the points +/- 1. Several properties of such new family are considered, in particular, the three-term recurrence relation and the representation as basic hypergeometric series. (C) 2012 Elsevier Inc.
