Ultraproduct,any class . of .-ary multirelations either . or its complement is induced, and also that any finite intersection of induced classes is an induced class (and therefore nonempty). By the compactness theorem (2.2.3), the intersection of all logical classcs induced by ℱ is not empty; in fact, it is a logical equivalence class, known as the . ℱ.
