| Abstract | |
Applying concepts of quantum mechanics and kinetic theory we show a re-derivation of Boltzmann equation for the Cosmic Microwave Background (CMB) polarization. We show the equivalence between our derivation and those already known ( [1], [2], [3] ) and also that these derivations correspond to take into account the effect, on the photon polarization, of two Thompson scattering on electrons while decoupling from matter. We adress ourselves, then, to give a complete formalism for the CMB polarization problem in real space, as started in [4] in a special case. Besides the possibility of complete treatment of the problem in real space, we recover the geometry that describes it and that tha causal relations are satisfied. (AU) | |
