Action based approach to dissipative relativistic fluid systems
G. L. Comer, N. Andersson, T. Celora +1
We develop an action principle for a relativistic two-fluid system with dissipation. The specific constituents of the model - which serves as a proof of principle - are particles a…

Linearizing a Non-linear Formulation for General Relativistic Dissipative Fluids
Thomas Celora, Nils Andersson, Greg L. Comer
Fully non-linear equations of motion for dissipative general relativistic multi-fluids can be obtained from an action principle involving the explicit use of lower dimensional matt…
