A remark on the transformations between different representations
Author(s): Zhang Yue
Abstract: The paper respectively studies the transformations of spin component operators and their eigen- functions from to representation. The studies demonstrate that if using the matrix of obtaining from the equation of transforming the eigenfunctions of and in terms of the transformation arising from Ref.  for all of the spin component operators from to representation, a negative symbol will occur in the result, which is not concordant with the commutation relation between and . Moreover, this matrix of transformation cannot be applied to the transformation of the eigenfunctions of or . It therefore concludes that with respect to the transformation of representation of an operator and its eigenfunctions, the matrix of transformation should be obtained from the equation of transforming the eigenfunctions of the same operator from the old to the new representation.
