Total-variation-diminishing time discretizations. (English) Zbl 0662.65081
For the approximate solution of hyperbolic conservation laws $$u_ t+\sum^{d}_{i=1}f_ i(u)_{x_ i}=0$$ for $$u\in {\mathbb{R}}^ m$$ and $$x\in {\mathbb{R}}^ d$$ difference schemes with the property of diminishing the total variation are a successful tool. In the present paper the scalar, one-dimensional case is considered and discussed, only. For steady state calculations, in which time accuracy is not important, a class of Runge-Kutta m-step time discretizations with a large CFL number is presented. On the other hand, for time-dependent problems a class of high order multilevel time discretizations with the total variation diminishing property is outlined.
