A method to study the Krall and q-Krall polynomials

[摘要] We describe a method allowing to obtain new results in studying the Krall and q-Krall polynomials. In particular, we establish the criterion for orthogonal polynomials to be eigenfunctions of 2Nth-order q-differential operator, This criterion is an exact q-analogue of corresponding Krall's criterion.
