POSSIBLE WORLDS AND MANY TRUTH VALUES
... each j exactly one qij holds, and let α∗ be γ ⇒ β. Then α∗ is a formula of K valid on exactly the same frames as α, as required. Formal systems in K are assumed to have just the usual rules (Substitution, Detachment, Necessitation), and at least the axioms of the system K. If M is standard, then for ...
