Dissipative Hyperbolic Systems: the Asymptotic Behavior of Solutions

2008

In this talk we shall review some recent results about qualitative behavior of smooth solutions to the Cauchy problem for general hyperbolic symmetrizable m-dimensional systems of balance laws of the form ut+ m∑ α= 1 (fα (u)) xα= g (u),(1) with the initial condition u (x, 0)= u0 (x),(2) where u=(u1, u2)∈ Ω⊆ Rn1× Rn2, with n1+ n2= n. We assume that there are n1 conservation laws in the system, namely that we can take g (u)=
