Operations, Collections and Sets within a General Axiomatic Framework,ch foundational theories appear in (see also ). Further investigations, along theses lines, have been carried out by various mathematicians, logicians and computer scientists since Spring 1994, starting from the “Basic Theories” introduced in (see, e.g., ).

A First-Order Effect and Modal Propositional Formulas,ss theorem. However, by the Lindström theorem (Theorem 2.5.4 ) these effects are very strong: both theorems together characterize first-order logic completely. It is natural to raise the question: what specific properties of first-order formulas are true for modal formulas (on interesting classes of frames).
