  In this paper we present some new equations which we call Yang-Mills-Proca
equations (or generalized Proca equations). This system of equations is a
generalization of Proca equation and Yang-Mills equations and it is not gauge
invariant. We present a number of constant solutions of this system of
equations in the case of arbitrary Lie algebra. In details we consider the case
when this Lie algebra is Clifford algebra or Grassmann algebra. We consider
solutions of Yang-Mills equations in the form of perturbation theory series
near the constant solution.
