This paper analyses the computational complexity of the model checking problem for Higher Order Fixpoint Logic – the modal µ-calculus enriched with a typed λ-calculus. It is ha...
Higher-Order Fixpoint Logic (HFL) is a hybrid of the simply typed λ-calculus and the modal µ-calculus. This makes it a highly expressive temporal logic that is capable of express...
We study (collapsible) higher-order pushdown systems -- theoretically robust and well-studied models of higher-order programs -- along with their natural subclass called (collapsi...
Abstract. We introduce model-checking games that allow local secondorder power on sets of independent transitions in the underlying partial order models where the games are played....
Abstract. This paper analyses the complexity of model checking Fixpoint Logic with Chop – an extension of the modal µ-calculus with a sequential composition operator. It uses tw...
