CCS for Trees

Logic in Computer Science 2013-06-10 v1

Abstract

CCS can be considered as a most natural extension of finite state automata in which interaction is made possible thanks to parallel composition. We propose here a similar extension for top-down tree automata. We introduce a parallel composition which is parameterized by a graph at the vertices of which subprocesses are located. Communication is allowed only between subprocesses related by an edge in this graph. We define an observational equivalence based on barbs as well as weak bisimilarity equivalence and prove an adequacy theorem relating these two notions.
