Most of that work has used standard Kripke structures to model knowledge, where an agent knows a fact ϕ if ϕ is true in all the worlds that the agent considers possible. While this ap ...

... Every logical equivalence that we’ve learned applies to predicate logic statements. For example, to prove ~x D, P(x), you can prove x D, ~P(x) and then convert it back with generalized De Morgan’s. To prove x D, P(x) Q(x), you can prove x D, ~Q(x) ~P(x) and convert it back using the ...

THE SEMANTICS OF MODAL PREDICATE LOGIC II. MODAL
... §1. Introduction. In [10] we have developed a semantics that is complete with respect to first- and weak second-order modal predicate logics. This semantics was in addition quite elementary, which was already a great step forward from the previous semantics by Ghilardi [6] and by Skvortsov and Sheht ...

... For example, if the context is number theory, and we are asked to prove that the product of two even integers is also even, we can use knowledge about number theory. In particular, we could use the fact that an even integer is divisible by 2, or that an even integer m can be rewritten as 2k for some ...

Logic contains rules and techniques to formalize statements, to make them precise. Logic is studied by philosophers, mathematicians and computer scientists. Log ...
