Arithmetic assertions can be written in first-order logic with the predicate symbol <, the function symbols + and *, and the constant symbols 0 and 1. Additional predicates can also be defined with ...

Propositional Calculus, Predicate Calculus, First Order Logic, and Higher Order Logic are completed. Due to S4, S5, and D being very simple in hyperslate, they are not going to be included in the ...

Logique et Analyse is an international, peer-reviewed journal that publishes research in logic, philosophy of logic and/or mathematics, argumentation-theory, and analytical philosophy, broadly ...

The course begins with a simple system called sentential or propositional logic, which despite its simplicity captures a significant range of important arguments. The course then focuses on ...

We investigate the relationship between recursive enumerability and elementary frame definability in first-order predicate modal logic. On one hand, it is well known that every first-order predicate ...

Coalgebraic modal logic serves as a unifying framework to study a wide range of modal logics beyond the relational realm, including probabilistic and graded logics as well as conditional logics and ...

The Journal of Philosophical Logic provides a forum for work at the crossroads of philosophy and logic, old and new, with contributions ranging from conceptual to technical. Accordingly, the Journal ...
