Nature of problem:The computer programs developed to produce the Einstein field and matter evolution equations and also the Liouville operator for the relativistic Boltzmann equation find a direct application in the study of general relativistic dynamics of astrophysical objects and their radiation counterpart (for example, in relativistic neutrino transport and gravitational wave emission). | ||

Solution method:The 3+1 formalism of General Relativity which recasts the Einstein and Matter equations in a suitable form to solve them numerically is employed to write the programs. The relativistic transport theory developed by Lindquist is used to describe neutrino propagation in curved spaces. |
