and analogical expression may be derived for chronological coupling of operators of electro- magnetic field, generated by magnetic charges, Because only vector potential A$_{e}$ enters in the equation (41), and only pseudovector- potential B$_{g}$ enters in the equation (42), the chronological coupling of operators of these potentials, expressed via Green function of motion equations, is equal zero Hence, as accordingly to (28), (29) the effective potential A$_{g}$ is a linear function of B$_{g}$ , and the effective potential B$_{e}$ is a linear function of A$_{e}$ , chronological couplings are also equal zero. Using expression (34) for A$_{g}$ ( x ), we obtain for the chronological coupling of operators A$_{g}$ (0) and B$_{g}$ ( y ):  0  x =0 By virtue of the homogeneity of the space-time and the arbitrariness of y in (49) we can conclude, that Similarly, for electromagnetic field, generated by electrical charges, Element of the S -matrix, corresponding to the interaction of elementary particle with magnetic charge and elementary particle with electrical charge, is a sum of terms, propor- tional to the chronological coupling (50) or (51), and so it proves to be equal zero; therefore, 11 〈 T { B k g ( x ) B l g ( y ) }〉 = i 4 πg $^{kl}$Dc $_{0}$( x − y ) .
