| Outline of Final Research Achievements |
Ultradiscretization is a limiting procedure transforming a given difference equation into a cellular automaton. The cellular automaton constructed by this procedure preserves the essential properties of the original equation, such as the structure of exact solutions for integrable equations.
During the research period, cellular automaton analogs of reaction-diffusion systems which are not an integrable system are constructed by the ultradiscretization. The shape, behavior and stability of the solutions in ultradiscrete systems are similar to those in continuous systems.
