Equations of radiation gas dynamics in tetrad form for astrophysical applications (Q581184)

This paper studies the astrophysical problem of radiation gas dynamics in curved space time by using the special relativistic equations in the Fermi-Walker frames. These are Lorentz-orthonormal frames obtained by parallel transport along a curve, here assumed to be locally co-moving with the average mass of the fluid. This paper presents an extensive review of this problem from both the physical and the mathematical viewpoints.
