Computational Mathematics Laboratory
Expressing complicated phenomena with simple rules
In recent years, we have seen a rapid advancement in “ultradiscretization,” a technology to identify the essential structures of natural phenomena, which are discretionally expressed in model equations. Cellular automaton — which is one of ultradiscrete equations and a completely discrete model consisting of “0s” and “1s” — is used to describe complicated phenomena such as traffic jams and ecosystems. Our laboratory conducts research on numerical calculation methods, which serve as the foundation for building mathematical models using discrete and ultradiscrete equations, in addition to numerical simulations.
