Abstract. Spatial conjunction is a powerful construct for reasoning about dynamically allocated data structures, as well as concurrent, distributed and mobile computation. While re...
My talk will be a survey of recent results about the quest for a logic capturing polynomial time. In a fundamental study of database query languages, Chandra and Harel [4] first ra...
CLF (Concurrent LF) [CPWW02a] is a logical framework for specifying and implementing deductive and concurrent systems from areas, such as programming language theory, security prot...
Abstract. We present the first terminating tableau calculus for basic hybrid logic with the difference modality and converse modalities. The language under consideration is basic m...
We investigate whether identification constraints such as keys and functional dependencies can be granted full status as a concept constructor in a Boolean-complete description log...
