(mathematics)
For a tensor field at a point P of an affine space, a new tensor field equal to the difference between the derivative of the original field defined in the ordinary manner and the derivative of a field whose value at points close to P are parallel to the value of the original field at P as specified by the affine connection.

Following the mathematical logic and the symmetry rules of Dirac; Majorana in contradiction to Dirac, showed that such an absolute differentiation is not possible, because both the fermions and the boson can contain their opposites within themselves as the dialectical unity of the opposites.
Exact details of each report were not given, so absolute differentiation between them was not possible.
