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 ...

The journal explores symbolic logic and foundations of mathematics relevant to the philosophy and methodology of science; and those facets of the ethics, history and sociology of science which are ...

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