✦ Synopsis


Two approaches to modelling surface erosion are described which can be used to explain the development of geomorphological features. The first approach uses non-linear wave theory and shows how surface gradient discontinuities can arise as the erosion of an initially smooth surface proceeds. For isotropic erosion, surface shapes may be predicted by a simple application of the Huyghens wavefront construction and Snell's law at media boundaries. A second approach uses a computational cellular method. The general shapes predicted by the computer simulations are shown to agree with those determined from the wave approach. The application of the cellular method to problems of geomorphological interest are discussed.

## Abstract In this paper we give a new proof of Richardson's theorem [31]: a global function __G__~𝔸~ of a cellular automaton 𝔸 is injective if and only if the inverse of __G__~𝔸~ is a global function of a cellular automaton. Moreover, we show a way how to construct the inverse cellular automaton

We study the computational complexity of several problems with the evolution of configurations on finite cellular automata. In many cases, the problems turn out to be complete in their respective classes. For example, the problem of deciding whether a configuration has a predecessor is shown to be N
