Towards Fully Automated Axiom Extraction for Finite-Valued Logics
Abstract. We implement an algorithm for extracting appropriate collections of classic-like sound and complete tableaux rules for a large class of finite-valued logics. Its output c...

A New Meta-complexity Theorem for Bottom-Up Logic Programs
Abstract. Nontrivial meta-complexity theorems, proved once for a programming language as a whole, facilitate the presentation and analysis of particular algorithms. This paper give...

Undecidability of Interval Temporal Logics with the Overlap Modality
We investigate fragments of Halpern-Shoham’s interval logic HS involving the modal operators for the relations of left or right overlap of intervals. We prove that most of these...

Defeasible Logic: Agency, Intention and Obligation
We propose a computationally oriented non-monotonic multi-modal logic arising from the combination of agency, intention and obligation. We argue about the defeasible nature of thes...

Proof Terms for Simply Typed Higher Order Logic
Abstract. This paper presents proof terms for simply typed, intuitionistic higher order logic, a popular logical framework. Unification-based algorithms for the compression and re...
