Model checking is emerging as a practical tool for detecting logical errors in early stages of system design. We investigate the model checking of sequential hierarchical (nested) systems, i.e., finite-state machines whose states themselves can be other ...

We introduce a transformation system for concurrent constraint programming (CCP). We define suitable applicability conditions for the transformations that guarantee the input/output CCP semantics is also preserved when distinguishing deadlocked ...

Several recent studies have introduced lightweight versions of Java: reduced languages in which complex features like threads and reflection are dropped to enable rigorous arguments about key properties such as type safety. We carry this process a step ...
