  The functional space of biquaternions is considered on Minkovskiy space. The
scalar-vector biquaternions representation is used which was offered by W.
Hamilton for quaternions. With introduction of differential operator - a mutual
complex gradient (bigradients), which generalize the notion of a gradient on
biquaternions space, biquaternionic wave (biwave) equations are considered,
their invariance for group of the Lorentz-Puancare transformations is shown and
their generalized solutions are obtained.
  Biquaternionic form of generalized Maxwell-Dirac equation is constructed and
its solutions are researched on base of the differential biquaternions algebra.
Its generalized decisions are built with use of scalar potential. The new
equation for these potential are constructed which unites known equations of
quantum mechanics (Klein-Gordon and Schrodinger Eq.). The nonstationary,
steady-state and harmonic on time scalar fields and generated by them the
spinors and spinors fields in biquaternionic form are constructed.
