Explicit expressions for optical scalars in gravitational lensing from
general matter sources
   [PDF]

Emanuel Gallo, Osvaldo M. Moreschi
We present explicit expressions for the optical scalars and the deection angle in terms of the energymomentum tensor components of matter distributions. Our work generalizes standard references in the literature where normally stringent assumptions are made on the sources.
