General first-order constitutive equations for a relativistic dissipative multi-component fluid in the presence of a weak background electromagnetic field
J. Félix Salazar, Ana Laura García-Perciante, Olivier Sarbach
In this work we establish general constitutive equations for a relativistic plasma composed of an arbitrary number of classical, charged, and chemically non-reacting species in the…

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…

On the illposedness and stability of the relativistic heat equation
A. L. García-Perciante, Oscar. Reula
In this note we analyze, in terms of a simple example, the incompatibility of parabolic evolution and general covariance. For this we introduce a unit time-like four-vector and stu…
