Researchers working on the semantics of programming languages came together in The Netherlands in June 1992 for a workshop on Semantics - Foundations and Applications. This volume is based on the meeting and contains material prepared by the lecturers after the meeting took place. The volume includes papers on a wide range of topics in both foundationsand applications, including: - Comparative domain theory, category theory, information systems, - Concurrency: process algebras, asynchronous communication, action semantics, trace nets, process refinement, concurrent constraint programming, - Predicate transformers, refinement,weakest preconditions, - Comparative semantics of programming concepts, full abstraction, - Reasoning about programs: total correctness, epistemic logic, - Logic programming, - Functional programming: sequentiality, integration with concurrency, applied structured operational semantics. The workshop was an activity of the project REX (Research andEducation in Concurrent Systems) sponsored by the Netherlands NFI (NationaleFaciliteit Informatica) Programme.
