| Abstract: | We consider the Cauchy problems for both scalar viscous conservation law and psystem with viscosity, the corresponding riemann problems have the nonlinear waves as the weak solutions, i. e. the rarefaction wave, the shock wave or their superpositions, depending on the data. Our purpose is to show that the solutions to the cauchy problems end to the rarefaction wave, viscous shock wave or their superposions, respectively. Fundamental results are proved via the L2-energy method, and the recent results are surveyed. Some cases are proposed as open problems. |
