B. Fiedler et S. Liebscher, Generic Hopf bifurcation from lines of equilibria without parameters: II. Systems of viscous hyperbolic balance laws, SIAM J MATH, 31(6), 2000, pp. 1396-1404
We investigate viscous shock profiles of the Riemann problem for systems of
hyperbolic balance laws. Even strictly hyperbolic flux terms together with
a nonoscillating kinetic part can lead to oscillating viscous shock profil
es. They appear near a Hopf-like bifurcation point of the traveling wave eq
uation.
