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: 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…

On Extended Thermodynamics: From Classical to the Relativistic Regime

Jose Felix Salazar, Thomas Zannias

The recent monumental detection of gravitational waves by LIGO, the subsequent detection by the LIGO/VIRGO observatories of a binary neutron star merger seen in the gravitational w…

On the Integrability of the Geodesic Flow on a Friedmann-Robertson-Walker Spacetime

Francisco Astorga, J. Felix Salazar, Thomas Zannias

We study the geodesic flow on the cotangent bundle of a Friedman-Robertson-Walker spacetime (M, g). On this bundle, the HamiltonJacobi equation is completely separable and this sep…
