Description

Symbolica.m is a package for computer experiments in symbolic dynamics. Directed labeled and unlabeled graphs are the primitive objects and they are used to represent shift spaces. Implemented functions include direct products, fibre products, labeled products, the subset construction and state splitting. There are also implementations of Boolean functions (e.g. IrreducibleQ, ResolvingQ, EssentialQ) and invariants for shift spaces (e.g. the Zeta function).
