Jones 4-spinors for the partially polarized light

The known group-theory based description of constructing of 4-tensors based on the second rank 4-spinor permits to introduce definition for Jones 4-spinor of a partially polarized light and relates this object with Stokes 4-vector and Stokes antisymmetric 4-tensor. It provides us with extension of the known attitude to the problem when only Jones 2-spinors relevant to a completely polarized light are used.
