 The equation involves matrices which obey the Duffin–Kemmer–Petiau algebra.The work leading to the DKP equation, culminating in Kemmer's article, has been quoted as "the first attempt at writing down a satisfactory relativistic theory of elementary particles beyond the electron", and these equations have later been brought in unified form with the Dirac equation by Homi J. Bhabha.Nicholas Kemmer Road in Edinburgh University's King's Buildings complex is named in his honour.
