Generic Hopf Bifurcation From Lines of Equilibria Without Parameters: II. Systems of Viscous Hyperbolic Balance Laws

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 profiles. They appear near a Hopf-like bifurcation point of the traveling wave equation.

Stable, Oscillatory Viscous Profiles of Weak Shocks in Systems of Stiff Balance Laws

This paper is devoted to a phenomenon in hyperbolic balance laws, first described by Fiedler and Liebscher [2], which is similar in spirit to the Turing instability. The combination of two individually stabilising effects can lead to quite rich dynamical behaviour, like instabilities, oscillations, or pattern formation. Our problem is composed of two ingredients. First, we have a strictly hyper...

The Identi cation ofFractional ARIMA

For the fractional ARIMA model, we demonstrate that wrong model speciication might lead to serious problems of inference in nite samples. We assess the performance of various model selection criteria when the true model is fractionally integrated and the alternatives of interest are ARMA and fractional ARIMA models. The likelihood of successful identiication increases substantially with rising ...
