Abstract

We present a systematic way to construct ultra-discrete versions of the Painlevé equations starting from know discrete forms. These ultra-discrete equations are generalised cellular automata in the sense that the dependent variable takes only integer values. The ultra-discrete Painlevé equations have the properties characteristic of the continuous and discrete Painlevé's, namely coalescence cascades, particular solutions and auto-Bäcklund relations.
