Formal verification methods are used only sparingly in software development. The most successful methods to date are based on the use of model checking tools. To use such he user ...
We present a thorough study of Propositional Dynamic Logic over a variation of labeled transition systems, called accelerated labelled transition systems, which are transition sys...
Traditionally, infinite databases were studied as a data model for queries that may contain function symbols (since functions may be expressed as infinite relations). Recently, th...
