Dirac-type tensor equations with non-Abelian gauge symmetries on   pseudo-Riemannian space
  We suggest a so-called Dirac type tensor equation with nonabelian gauge symmetry on pseudo-Riemannian space. This equation reproduce some of the properties of spinor Dirac equation. A geometrical interpretation of results in terms of Riemannian geometry is given.
