Nonlinear Causality and Strong Hyperbolicity of Einstein-Israel-Stewart Theories of Transient Relativistic Fluid Dynamics
Ian Cordeiro, Enrico Speranza, Fábio S. Bemfica +2
We present the first complete analysis of nonlinear causality and local well-posedness for a very general class of bulk and shear viscous theories of relativistic transient fluid d…

Nonlinear causality of Israel-Stewart theory with diffusion
Ian Cordeiro, Fábio S. Bemfica, Enrico Speranza +1
We present the first fully nonlinear causality constraints in dimensions for Israel-Stewart theory in the presence of energy and number diffusion in the Eckart and Land…

Nonlinear causality and strong hyperbolicity of baryon-rich Israel-Stewart hydrodynamics
Ian Cordeiro, Fábio S. Bemfica, Enrico Speranza +1
We present the first set of fully-nonlinear, necessary and sufficient conditions guaranteeing causal evolution of the initial data for the Israel-Stewart hydrodynamic equations wit…
