Abstract:
We consider the polynomials  obtained from the little  -Jacobi polynomials  by inserting a discrete mass  at  in the orthogonality measure. We show that for  , the polynomials  are eigensolutions of a linear  -difference operator of order  with polynomial coefficients. This provides a  -analog of results recently obtained for the Krall polynomials.
