Abstract. Controlled Query Evaluation (CQE) offers a logical framework to prevent a user of a database from inadvertently gaining knowledge he is not allowed to know. By modeling t...
This paper is the first in a series of three related papers on modal methods in interpretability logics and applications. In this first paper the fundaments are laid for later res...
This paper presents a complete axiomatization of two decidable propositional realtime linear temporal logics: Event Clock Logic (EventClockTL) and Metric Interval Temporal Logic w...
The SLG-WAM of XSB Prolog soundly implements the Well-Founded Semantics (WFS) for logic programs, but in a few pathological cases its engine treats atoms as undefined that are true...
A complete and decidable propositional logic for reasoning about states of probabilistic sequential programs is presented. The state logic is then used to obtain a sound Hoare-styl...
