Abstract

A bigraphical reactive system (BRS) involves bigraphs, in which the nesting of nodes represents locality, independently of the edges connecting them. BRSs represent a wide variety of calculi for mobility, including the π-calculus. This short essay explains how bigraphs compose, and uses the π-calculus to illustrate how they already provide elements of a unifying theory for calculi of mobile interactive processes.
