Proposition: A declarative statement that is either true or false Truth Value: Indicates whether the proposition is actually true or false. The truth value can be true, false, unknown, or a matter of ...

Abstract: We introduce a propositional and a first-order logic for reasoning about discrete linear time and finitely additive probability. The languages of these logics allow formulae that say ...
