Dual transformations in non-Abelian gauge field theory

On the basis of quaternion formulation of non-Abelian gauge field equations it is shown, that there is a possibility of their representation in the form, invariant under the same dual transformations, which take place in electrodynamics. The procesurte suggested is just in the case of inclusion of gauge field interaction with spinor fields and Higgs fields. All the necessary ratios in tensor form are also presented
