Abstract
Zielonka's Theorem characterizes recognizable subsets of free partially commutative monoids in terms of asynchronous automata.
Here, we prove two results closely related to Zielonka's Theorem: first, we give a new representation theorem for finite monoids; next, we characterize the class of recognizable subsets of free partially commutative monoids in terms of a new model of distributed system with bounds on space and communication complexity.
