On the algebra of the meson matrices
Harish-chandra Harish-Chandra · Mathematical Proceedings of the Cambridge Philosophical Society · 1947
It is shown that the algebra of the Duffin-Kemmer matrices can be handled quite neatly by introducing an extra dimension and by using the Γ-formalism of an earlier paper (3). By this means it is possible to derive identities similar to the De Broglie-Pauli identities for the Dirac matrices. To complete the analogy a Γ-formalism is also set up for the Dirac matrices.
