" General form of -matrices of the first order wave equations in 16-dimensional representation"

The most general expressions of the -matrices of the first order
wave equations in 16-dimensional representations in the direct product
(DP),
Gelfand (G), and Kemmer-Duffin-Petiau (KDP) basises are computed. In
the general case, 16 arbitrary parameters arises. Depending on these
parameters, the -matrices satisfy the KDP-, the Dirac- and a new
algebras, so that corresponding equations may describe both, the bosons
and fermions equally. The classical KDP theory describes spin 0 and 1
particles only.
It appears, that the reduction 1 + 5 + 10 only in a special case is
possible and in generally. Unitary transformations, connecting
the quantities of DP-basis with ones of G- and KDP-basises, are
expressed.
