Theory and Practice of Formal Methods : Essays Dedicated to Frank de Boer on the Occasion of His 60th Birthday

This Festschrift volume has been published in honor ofFrank de Boer, on the occasion of his 60th birthday.
Frank S. de Boer is a prominent member of the research community in formalmethods and theoretical computer science. A brief look at his lengthypublication list reveals a broad area of interest and a versatile modusoperandi with: logic and constraint programming; deductive proof systems,soundness, and completeness; semantics, compositionality, and full abstraction;process algebra and decidability; multithreading and actor-based concurrency;agent programming, ontologies, and modal logic; real-time systems, timedautomata, and schedulability; enterprise architectures, choreography, andcoordination; testing and runtime monitoring; and cloud computing and service-levelagreements. For a while, he also liked failures, especially in semantics, andoptimistically concluded with the failure of failures. In fact, Frank has anopportunistic approach to research. Rather than seeing obstacles, he findsopportunities.
