Analytic Results for (Ultra-discrete) Cellular Automata
Wednesday 4th October 14:05-14:55pm,
Carslaw Building Room 373.
Cellular automata (CA) have been widely adopted in the sciences as
simple but powerful models of the real world. The complex patterns
produced by their long-time behaviours are used to confirm the
correctness of scientific hypotheses underlying the model. However,
the analysis essential for testing scientific hypotheses appears to be
missing. We show the beginnings of the mathematical analysis needed by
reviewing the connection that leads from differential equations to
ultra-discrete equations which are extended CA. New results for
ultra-discrete equations include a test for integrability and results
on solvability through associated linear problems.
