RT Journal Article T1 Extended Krein-Adler theorem for the translationally shape invariant potentials A1 Gómez-Ullate Otaiza, David A1 Grandati, Yves A1 Milson, Robert AB Considering successive extensions of primary translationally shape invariant potentials, we enlarge the Krein-Adler theorem to mixed chains of state adding and state-deleting Darboux-Backlund transformations. It allows us to establish novel bi-linear Wronskian and determinantal identities for classical orthogonal polynomials.
