TL;DR: Nonquantum entanglement or inseparability between the polarization and spatial degrees of freedom of an electromagnetic beam whose polarization is not homogeneous is shown to provide the physical basis to resolve this issue in a definitive manner.

TL;DR: In this article, the geometry of the generalized Bloch sphere Ω3, the state space of a qutrit, is studied, and closed form expressions for the generalized bloch sphere, its boundary, and the set of extremals are obtained by use of an elementary observation.

TL;DR: In this article, the Mueller-Stokes formalism is extended to the case of partially coherent partially polarized electromagnetic beams, and additional constraints that a pre-Mueller matrix mapping Omega((pol)) into itself needs to meet in order to be an acceptable physical Mueller matrix are investigated.

TL;DR: There is a need to extend the Mueller-Stokes formalism to beams wherein the polarization and spatial dependence are generically inseparably intertwined, and additional constraints that a pre-Mueller matrix M mapping Omega((pol)) into itself needs to meet in order to be an acceptable physical Mueller matrix.

TL;DR: The geometry of the generalized Bloch sphere is studied in this article, where closed form expressions for the generalized blob sphere, its boundary, and the set of extremals are obtained by use of an elementary observation.
