Abstract. This article extends and improves work on tableau-based decision methods for hybrid logic by Bolander and Bra¨uner [5]. Their paper gives tableau-based decision procedur...
A secure timeline is a tamper-evident historic record of the states through which a system goes throughout its operational history. Secure timelines can help us reason about the t...
In this work, we improve on existing work that studied the relationship between the proof system of modern SAT solvers and general resolution. Previous contributions such as those ...
I describe the mechanisation in HOL of some basic -calculus theory, using the axioms proposed by Gordon and Melham [4]. Using these as a foundation, I mechanised the proofs from C...
Abstract. The first part of this paper presents a new approach for automatically proving nontermination of string rewrite systems. We encode rewrite sequences as propositional for...
