vector space), components of pseudo-tensor T of weight W , which is r -times contra-variant and s -times co-variant, are transformed according to the law (see, for example, [13]): In contrast to the ordinary tensor’s component transformation, there is a factor in the form of Jacobian of coordinate transformation of power W in equation (9). The weight of the product of two tensors equals the summarized weight of tensors of each factor and convolution of each pair of indices, consisting of the identical upper and lower indices, does not change the weight of tensor; all pseudo-tensors considered in the paper have weight ± 1; in particular, a magnetic charge is a pseudo-scalar, see below, and, hence, we are not far from the fore-quoted Weinberg statement. The left-hand part of equation (4a) represents by itself a tensor of the third rank, which is antisymmetric in all indices. Having lowered indices of this tensor, multiplied by e mlik and performed convolution with respect to three pairs of identical indices, we obtain equation The relation between components of pseudo-tensor F ⋆ $_{A$_{e}$}$, which is dual to F$_{A}$$_{e}$ , and compo- nents of (three-dimensional) vectors of electrical field E and magnetic field H is described as i.e. in pseudo-tensor F $_{A$_{e}$}$, as compared to tensor F$_{A}$$_{e}$ , components of (three-dimensional) vectors of the electrical and magnetic fields change places.
