Abstract Interpretation from Buchi Automata

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We describe the construction of an abstract lattice from a given Buchi automata. The abstract lattice is finite and has the following key properties. (i) There is a Galois connection between it and the (infinite) lattice of languages of finite and infinite words over a given alphabet. (ii) The abstraction is faithful with respect to acceptance by the automaton. (iii) Least fixpoints and ω-iterations (but not in general greatest fixpoints) can be computed on the level of the abstract lattice.

This allows one to develop an abstract interpretation capable of checking whether finite and infinite traces of a (recursive) program are accepted by a policy automaton. It is also possible to cast this analysis in form of a type and effect system with the effects being elements of the abstract lattice.

While the resulting decidability and complexity results are known (regular model checking for pushdown systems) the abstract lattice provides a new point of view and enables smooth integration with data types, objects, higher-order functions which are best handled with abstract interpretation or type systems.

We demonstrate this by generalising our type-and-effect systems to object-oriented programs and higher-order functions.
