Commutative ordinary differential operators. II.—The identity P <sup>n</sup> = Q <sup>m</sup>
In a paper previously communicated to the Society we developed the general theory of ordinary differential operators P, Q of interprime orders m, n , which satisfy the commutative identity PQ = QP. Such a pair of operators also satisfy a second identity f (P, Q) ≡ P n — …
