Jan 01, 1974 · For hyperbolic partial differential equations it is essential to control the dispersion, dissipation, and the propagation of discontinuities. This is easily done by using suitable difference approximations. The main disadvantage of finite difference methods is that it may be difficult to handle boundaries properly.

Solution of hyperbolic equations is perhaps the area in which finite difference methods have most successfully continued to play an important role. This is particularly true for nonlinear conservation laws, which, however, are beyond the scope of this elementary presentation. Here we begin in Sect. 12.1 with the pure initial-value problem for a ...
