Consider the Wronskians of the classical Hermite polynomials H λ , l ( x ) : = Wr ( H l ( x ) , H k 1 ( x ) , … , H k n ( x ) ) , l ∈ Z ≥ 0 \ { k 1 , … , k n } , whereandis a partition. Gómez-Ullate et al. showed that for a special class of partitions the corresponding polynomials are orthogonal and dense among all polynomials with respect to a certain inner product, but in contrast to the usual case have some degrees missing (so-called exceptional orthogonal polynomials). We generalise their results to all partitions by considering complex contours of integration and non-positive Hermitian products. The corresponding polynomials are orthogonal and dense in a finite-codimensional subspace ofsatisfying certain quasi-invariance conditions. A Laurent version of exceptional orthogonal polynomials, related to monodromy-free trigonometric Schrödinger operators, is also presented.
