A lattice-theoretic characterization of safety and liveness
The distinction between safety and liveness properties is due to Lamport who gave the following informal characterization. Safety properties assert that nothing bad ever happens w...

Monadic datalog over finite structures with bounded treewidth
Bounded treewidth and Monadic Second Order (MSO) logic have proved to be key concepts in establishing fixed-parameter tractability results. Indeed, by Courcelle's Theorem we ...
