Predicate logic is an extension of propositional logic. Here we consider what is called first-order predicate logic, abbreviated FOL (sometimes abbreviated PL1, not to be confused with the programming ...

This is a preview. Log in through your library . Abstract Global properties of canonical derivability predicates (the standard example is Pr() in Peano Arithmetic) are studied here by means of a ...

Abstract: We propose a logic-based approach for reasoning about (public-key infrastructure) PKI trust models. Our formalism uses the predicate calculus language to describe a PKI trust model with ...

Python package that provides an interface to work with classical propositional and first-order logic, based on my solutions to the textbook Mathematical Logic Through Python by Nisan and Gonczarowski ...

My father, Derek Goldrei, who has died unexpectedly on his 74th birthday, worked as a mathematician for the Open University and various Oxford University colleges for his entire career. Derek was born ...

A great deal of Java programming -- from conditional statements to iterative loops -- deals with the evaluation of true or false values. When you work with the JDK's Streams API and Lambda functions, ...

ABSTRACT: In this paper, we focus on investigation of the predicate transformer semantics of the contract language introduced by Back and von Wright in their book titled as “Refinement Calculus: A ...
