The correctness of the Z semantics of OWL is the theoretical foundation of using software engineering techniques to verify Web ontologies. As OWL and Z are based on different logi...
Inspired by the recent work on approximating classical logic, we present a procedure that approximates the modal logic K by determining a maximum limit of introspection. This proc...
We show how to reason, in the proof assistant Coq, about realistic programming languages using a combination of separation logic and heterogeneous multimodal logic. A heterogeneou...
We consider the non-orthodox proof rules of hybrid logic from the viewpoint of topological semantics. Topological semantics is more general than Kripke semantics. We show that the...
We pursue the program of exposing the intrinsic mathematical structure of the “space of proofs” of a logical system [AJ94b]. We study the case of Multiplicative-Additive Linea...
