Abstract: | Multiple Rayleigh scattering is examined in a semi-infinite atmosphere with uniformly distributed primary sources of partially
polarized radiation. The resulting linear polarization is described by a 2×2 matrix transfer equation. A matrix generalization
of Rybicki's two point Q-integral is obtained for this case. It is shown that the Volterra equation for the matrix source function for this problem
is a particular case of our Q integral. Applying the Laplace transform to it yields the matrix form of the Ambartsumyan-Chandrasekhar H-equation. The Volterra equation for Sobolev's matrix resolvent function is another simple consequence of this equation.
