Montague, Prior, von Wright and others drew attention to resemblances between modal operators and quantifiers. In this paper we show that classical quantifiers can, in fact, be regarded as "S5-like" ...

We give a completeness theorem for a logic with probability quantifiers which is equivalent to the logics described in a recent survey paper of Keisler [K]. This result improves on the completeness ...

Logic and geometric representations constitute an interdisciplinary framework that merges formal logical systems with spatial and diagrammatic structures. This field encompasses the study of ...

Marcus began her revolutionary work in modal logic during the late 1940s when she developed the Barcan formula, which developed the use of quantifiers in the field. Though Marcus initially came under ...

By incorporating unary operations analogous to universal and existential quantifiers, monadic structures offer a refined algebraic framework to capture predicate logics, including those with ...
