   Originated or taught by Diophantus, the Greek writer on
   algebra.

   {Diophantine analysis} (Alg.), that branch of indeterminate
      analysis which has for its object the discovery of

      squares or cubes; as, for example, to find values of x and
      y which make x^{2} + y^{2} an exact square.
