The Semantics of Modal Predicate Logic II. Modal Individuals Revisited
نویسنده
چکیده
We continue the investigations begun in [10]. We shall define a semantics that is build on a new notion of frame, called coherence frames. In these frames, objects are transcendental (world–independent), as in the standard constant–domain semantics. This will remove the asymmetry between constants and variables of the counterpart semantics of [10]. We demonstrate the completeness of (general) coherence frames with respect to firstand certain weak second–order logics as well as compare this notion of frame to counterpart frames as introduced in [10] and metaframe semantics, [13]. §

Structural Operational Semantics and Modal Logic, Revisited
A previously introduced combination of the bialgebraic approach to structural operational semantics with coalgebraic modal logic is re-examined and improved in some aspects. Firstly, a more abstract, conceptual proof of the main compositionality theorem is given, based on an understanding of modal logic as a study of coalgebras in slice categories of adjunctions. Secondly, a more concrete under...
متن کاملModal Foundations for Predicate Logic
The complexity of any logical modeling reeects both the intrinsic structure of a topic described and the weight of the formal tools. Some of this weight seems inherent in even the most basic logical systems. Notably, standard predicate logic is undecidable. In this paper, we investigatèlighter' versions of this general purpose tool, by modally`deconstructing' the usual semantics, and locating i...
متن کاملThe Semantics of Modal Predicate Logic I. Counterpart-Frames
We introduce a new semantics for modal predicate logic, with respect to which a rich class of first-order modal logics is complete, namely all normal first-order modal logics that are extensions of free quantified K. This logic is defined by combining positive free logic with equality PFL . = and the propositional modal logic K. We then uniformly construct—for each modal predicate logic L—a can...
متن کاملCoalgebraic Modal Logic in CoCasl
We extend the algebraic-coalgebraic specification language CoCasl by full coalgebraic modal logic based on predicate liftings for functors. This logic is more general than the modal logic previously used in CoCasl and supports the specification of a variety of modal logics, such as graded modal logic, majority logic, and probabilistic modal logic. CoCasl thus becomes a modern modal language tha...
متن کاملModal Kleene Algebra and Applications — A Survey —
Modal Kleene algebras are Kleene algebras with forward and backward modal operators, defined via domain and codomain operations. They provide a concise and convenient algebraic framework that subsumes various popular calculi and allows treating quite a number of areas. We survey the basic theory and some prominent applications. These include, on the system semantics side, wlp and wp calculus, P...
