Dominant Energy Condition and dissipative fluids in general relativity
Existing literature implements the Dominant Energy Condition for dissipative
fluids in general relativity. It is pointed out that this condition fails to
forbid superluminal flows, which is what it is ultimately supposed to do.
Tilted perfect fluids, which formally have the stress-energy tensor of
imperfect fluids, are discussed for comparison.Comment: Corrected typographical error in Eq. (31). Matches the version to
appear in Gen. Relativ. Gravi
