Generalized synchronization languages are a model used to describe the behaviors of distributed applications whose synchronization constraints are expressed by generalized synchronization expressions — an extension of synchronization expressions. Generalized synchronization languages were conjectured by Salomaa and Yu to be characterized by a semi-commutation. We show that this semi-commutation characterizes the images of generalized synchronization languages by a morphism-like class of rational functions.

Topics. Automata and formal languages, theory of parallel and distributed computation.
