Comment on Shock waves, part 3 by Uwe Brauer

Hi
Ok some sort of misunderstanding then.
I *was* thinking of the _isentropic_ case. In your post you didn’t say whether it is isentropic, but I assumed it were (I did not check your work with Floch, although I read it some time ago).

But now that you mentioned it, I will check whether Bressan’s results have been generalized to the case with a linear degenerate equation. If I find out I let you know.

Hi,

To my knowledge the uniqueness results of Bressan are limited to the case of systems of conservation laws which are genuinely nonlinear. Thus, they do not apply to the full Euler equations, which have one set of linearly degenerate characteristics, although they do apply to the isentropic case. This is what I was thinking of when I wrote this but I did not write it explicitly. If what I thought is out of date and there are now Bressan-type results applying to the full Euler equations then please let me know.
