Reasoning About Typicality in ALC and EL
In this work we summarize our recent results on extending Description Logics for reasoning about prototypical properties and inheritance with exceptions. First, we focus our attent...

Revision of DL-Lite Knowledge Bases
Abstract. We address the revision problem for knowledge bases (KBs) in Description Logics (DLs). This problem has received much attention in the ontology management and DL communit...

A machine-checked soundness proof for an efficient verification condition generator
Verification conditions (VCs) are logical formulae whose validity implies the correctness of a program with respect to a specification. The technique of checking software properti...

A Simple Class of Kripke-Style Models in Which Logic and Computation Have Equal Standing
We present a sound and complete model of lambda-calculus reductions based on structures inspired by modal logic (closely related to Kripke structures). Accordingly we can construct...

A Logic on Subobjects and Recognizability
We introduce a simple logic that allows to quantify over the subobjects of a categorical object. We subsequently show that, for the category of graphs, this logic is equally expres...

Maximal Decidable Fragments of Halpern and Shoham's Modal Logic of Intervals
In this paper, we focus our attention on the fragment of Halpern and Shoham's modal logic of intervals (HS) that features four modal operators corresponding to the relations &...

First-Order Logic with Reachability Predicates on Infinite Systems
This paper focuses on first-order logic (FO) extended by reachability predicates such that the expressiveness and hence decidability properties lie between FO and monadic second-o...

The free n-generated BL-algebra
The theory of Schauder hats is a beautiful and powerful tool for investigating, under several respects, the algebraic semantics of Lukasiewicz infinite-valued logic [CDM99], [MMM07...

Local Reasoning and Dynamic Framing for the Composite Pattern and Its Clients
Abstract. The Composite design pattern is an exemplar of specification and verification challenges for sequential object-oriented programs. Region logic is a Hoare logic augmente...
