Abstract:

Classical orthogonal polynomials on the real line possess a bispectrality property, i.e. they satisfy both 3-term recurrence relation and differential or difference eigenvalue relation. We show that special "classical" orthogonal polynomials on the unit circle  (OPUC) also possess similar property. We present a simple example of such classical OPUC related with the Jacobi polynomials.
