Path Constraints from a Modal Logic Point of View
We analyze several classes of path constraints for semistructured data in a unified framework and prove some decidability and complexity results for these constraints by embedding...

Multimodal Separation Logic for Reasoning About Operational Semantics
We show how to reason, in the proof assistant Coq, about realistic programming languages using a combination of separation logic and heterogeneous multimodal logic. A heterogeneou...
