Based on main observational characteristics of solar flare particle transport in the coronal, a mathematical description of coronal transport is proposed. A model is presented for solar cosmic-ray propagation in solar-terrestrial space of infinite, homogeneous orthotropic medium. A Green function to the propagation equation with source is found. The integral solution to the propagation equation with the source, as well as the analytical solution to the equation for a pulse point source, is obtained by using the Green function in the medium.
