Title: Exceptional orthogonal polynomials: recurrence formula and classicality

Abstract:

Exceptional orthogonal polynomials (EOPs) are introduced as a generalization of classical orthogonal polynomials (COPs). EOPs satisfy second-order differential equations and orthogonality relation although their several degrees are missing. EOPs are no longer COPs and hence they do not hold the properties as three term recurrence formula, classicality and so on. In this talk, I will review EOPs and discuss their properties.
