Abstract
The goal of this chapter is to show that the limit found by front tracking, that is, the weak solution of the initial value problem u t + f(u) x = 0, u(x, 0) = u 0(x), (7.1) is stable in L 1 with respect to perturbations in the initial data. In other words, if v = v(x, t) is another solution found by front tracking, then |u( · , t) − v( · , t)|1 ≤ C|u 0 − v 0|1 for some constant C. Furthermore, we shall show that under some mild extra entropy conditions, any weak solution coincides with the solution constructed by front tracking.
