This note describes Proof General, a tool for developing machine proofs with an interactive proof assistant. Interaction is based around a proof script, which is the target of a pr...
Abstract. A type-based certifying compiler maps source code to machine code and target-level type annotations. The target-level annotations make it possible to prove easily that th...
Abstract. The aim of this work is to characterize constructive real numbers through a minimal axiomatization. We introduce, discuss and justify 16 constructive axioms. Then we addr...
Abstract. In the FTA project in Nijmegen we have formalized a constructive proof of the Fundamental Theorem of Algebra. In the formalization, we have first defined the (constructiv...
Quantum information and computation is the new hype in physics. It is promising, mindboggling and even already applicable in cryptography, with good prospects ahead. A brief, rathe...
