Deciding Bisimilarity of Full BPA Processes Locally

Abstract

We propose a tableau algorithm to decide bisimilarity of guarded normed and unnormed BPA processes, which is very intuitive and direct. It also has the advantage of helping us to show that the equational theory proposed by Hüttel and Stirling for normed BPA systems is also complete for arbitrary guarded BPA systems. As a result, the first equational theory for full BPA processes is found.KeywordsBasic StepEquational TheoryOperational SemanticLabel Transition SystemFresh VariableThese keywords were added by machine and not by the authors.
