1. Consider the model on page 178 stated below: Look now in the second paragraph of page 191 under Numerical Example to see how one can derive the AD curve. As its 3 rd line says, "setting the ...

Within the class of nonlinear hyperbolic balance laws posed on a curved spacetime (endowed with a volume form), we identify a hyperbolic balance law that enjoys the same Lorentz invariance property as ...
