Pauli Matrices and the Theory of Representations of the Group of Rotations

Abstract

It is shown that Pauli Matrixes can be derived from irreducible rotation group representations of the weight =1/2, which in turn based on the system of infinitesimal (elementary) spatial rotations. The last permits to substantiate why Pauli matrixes can be so sufficiently used for modeling of physical rotations.Pauli matrices, Group rotations, spinor transformation, group of rotation
