The book begins with the basic principles for modeling concurrent and communicating systems, introduces different classes of properties (including safety and liveness), presents the notion of fairness, and provides automata-based algorithms for these properties. It introduces the temporal logics ...

The Liar Paradox: A Consistent and Semantically Closed Solution
... This thesis develops a new approach to the formal de nition of a truth predicate that allows a consistent, semantically closed de nition within classical logic. The approach is built on an analysis of structural properties of languages that make Liar Sentences and the paradoxical argument possible. ...
