We present a logic for reasoning about LOTOS behaviours which allows properties involving repeated patterns over actions and data to be expressed. The semantics of the logic is giv...
We develop an Answer Set Programming formalism based on Default Logic. We show that computing generating sets of extensions in this formalism captures all ΣP 2 search problems.
This paper proposes some variants of Temporal Defeasible Logic (TDL) to reason about normative modifications. These variants make it possible to differentiate cases in which, for ...
This paper outlines a sound and complete Hoare logic for a sequential object-oriented language with inheritance and subtyping like Java. It describes a weakest precondition calculu...
I present a new syntactical method for proving the Interpolation Theorem for the implicational fragment of intuitionistic logic and its substructural subsystems. This method, like...
