Modal Languages and Bounded Fragments of Predicate Logic
... What precisely are fragments of classical first-order logic showing “modal” behaviour? Perhaps the most influential answer is that of Gabbay 1981, which identifies them with so-called “finite-variable fragments”, using only some fixed finite number of variables (free or bound). This view-point has b ...

... a kind of an analytic subformula property limiting the proof search space. This property holds for proof systems enjoying the subformula property (the latter is a property that usually follows from cut elimination). The bounded proof property depends on an axiomatization of a logical system. That is ...

Truth-Functional Propositional Logic
... why the rules work or not. The uniformity, simplicity, and regularity of these arithmetical rules, and their applicability with minimal understanding, is shown by the existence of extremely simple artificial devices for effective arithmetical calculation such as the ancient abacus. Before any system ...

Reasoning about Action and Change
... To our knowledge, nobody so far tried to cope with the combinatorial problem and the overcommitment problem in a dynamic logic framework. A notable exception is the paper of Stephan & Biundo (1993) (see also Kautz, 1982; Morreau, 1992). In the language of firstorder dynamic logic they propose frame ...
