Matching conditions are crucial in determining the overall consistency properties of relativistic fluid dynamics. This paper derives transient fluid dynamics from kinetic theory without imposing a specific matching condition, and then examines how the choice of matching condition affects the equations of motion and transport coefficients.
Recent works have revealed that matching conditions play a major role in general consistency properties of relativistic fluid dynamics, such as causality, stability, and well posedness of the equations of motion. In this paper we derive transient fluid dynamics from kinetic theory, using the method of moments as proposed by Israel and Stewart, without imposing a specific matching condition. We then investigate how the equations of motion and their corresponding transport coefficients are affected by the choice of matching condition.
