Brenke–Chihara polynomials

Brenke–Chihara polynomials are a specific sequence of polynomials that arise in the context of combinatorics and orthogonal polynomials. They are related to various mathematical areas including approximation theory, numerical analysis, and probability theory. These polynomials can be defined recursively and are often characterized by certain orthogonality conditions concerning a weight function over an interval. The exact properties and applications can vary significantly depending on the context in which the polynomials are used.
