For a generalization, see Theorem 2.9 here (V. Kodiyalam, T. Lam, R. Swan, Determinantal ideals, Pfaffian ideals, and the principal minor theorem. Noncommutative rings, group rings, diagram algebras and their applications, 35-60, Contemp. Math., 456, Amer. Math. Soc., Providence, RI, 2008). I haven't found a more classical reference. | |
