R-Calculus, III: Post Three-Valued Logic

This third volume of the book series shows R-calculus is a Gentzen-typed deduction system which is non-monotonic, and is a concrete belief revision operator which is proved to satisfy the AGM postulates and the DP postulates. In this book, R-calculus is taken as Tableau-based/sequent-based/multisequent-based to preserve the satisfiability of the Theory/sequent/multisequent to revise, or sequent-based, to preserve the satisfiability of the sequent to revise. The R-calculi for Post and three-valued logic is given.

This book offers a rich blend of theory and practice. It is suitable for students, researchers and practitioners in the field of logic.

Discusses the algebraical and logical properties of tableau proof systems and R-calculi in many-valued logics Gives the R-calculi for propositional logic, description logics, propositional modal logic, logic programming etc. Inspires theoretic computer scientists by showing how R-calculus is developed into a series of complicated theories
