Theorem 6.5 Let τ be a modal similarity type. Any normal modal logic in a language for τ has the finite model property iffit has the finite frame property. Definition 6.6 (Strong Finite Model Property) Let Λ be a normal modal logic, M a set of finitely based models such that Λ = ΛM, and f a function mapping natural numbers to natural numbers.
