## The convergence rate of approximate solutions for nonlinear scalar conservation laws.(English)Zbl 0765.65092

Let $$\{v^ t(x,t)\}$$ be a $$\text{Lip}^ +$$-stable family of approximate solutions for $$u_ t+f(u)_ x=0$$ with $$C_ 0^ 1$$ initial data. If they are $$\text{Lip}'$$-consistent then they converge to the entropy solution with the rate $${\mathcal O}(\varepsilon)$$. $$L^ p$$ and pointwise error estimates follow.
