10. On integrability test for ultradiscrete equations
We consider an integrability test for ultradiscrete equations based on the

singularity confinement analysis for discrete equations. We show how

singularity pattern of the test is transformed into that of ultradiscrete

equation. The ultradiscrete solution pattern can be interpreted as a perturbed

solution. We can also check an integrability of a given equation by a

perturbation growth of a solution, namely Lyapunov exponent. Therefore,

singularity confinement test and Lyapunov exponent are related each other in

ultradiscrete equations and we propose an integrability test from this point of
