Relativistic dissipative fluids in the trace-fixed particle frame: Strongly hyperbolic quasi-linear first-order evolution equations
J. Félix Salazar, Ana Laura García-Perciante, Olivier Sarbach
In this paper we derive a new first-order theory of relativistic dissipative fluids by adopting the trace-fixed particle frame. Whereas in a companion letter we show that this theo…

Relativistic dissipative fluids in the trace-fixed particle frame: Hyperbolicity, causality, and stability
J. Félix Salazar, Ana Laura García-Perciante, Olivier Sarbach
We propose a first-order theory of relativistic dissipative fluids in the trace-fixed particle frame, which is similar to Eckart's frame except that the temperature is determined b…

Existence of the Chapman-Enskog solution and its relation with first-order dissipative fluid theories
A. L. García-Perciante, A. R. Méndez, O. Sarbach
The conditions for the existence of the Chapman-Enskog first-order solution to the Boltzmann equation for a dilute gas are examined from two points of view. The traditional procedu…
