Consider an abstract operator L which acts on monomials x n according to L x n= λ n x n+ ν n x n− 2 for λ n and ν n some coefficients. Let P n (x) be eigenpolynomials of degree n of L: L P n (x)= λ n P n (x). A classification of all the cases for which the polynomials P n (x) are orthogonal is provided. A general derivation of the algebras explaining the bispectrality of the polynomials is given. The resulting algebras prove to be central extensions of the Askey–Wilson algebra and its degenerate cases.
