摘要
We have obtained analytical exact solutions of the Dyer-Roeder equation in a cosmological model where creation of particles occurs at the expense of the gravitational field. We discuss the influences of inhomogeneities in the path of a light beam on the apparent diameter of astrophysical objects and consider both redshift independent and redshift dependent distributions of the inhomogeneities.
