The latter is more amenable to automatic manipulation and sheds light on the logical differences among different forms of bisimulation over algebras of name-passing processes. Symbolic transitions have the form[formula], whereφis a boolean combination of equalities on names that has to hold for the transition to take place, andαis standard aπ-calculus action. On top of the symbolic transition system, a symbolic bisimulation is defined that captures the standard ones. Finally, a sound and complete proof system is introduced for symbolic bisimulation. %Z An extended abstract of this paper appears in: B. Jonsson and J.
