We define dual and symmetric combinatory calculi (inequational and equational ones), and prove their consistency. Then, we introduce algebraic and set theoretical– relational and operational – semantics, and prove soundness and completeness. We analyze the relationship between these logics, and argue that inequational dual logics are the best suited to model computation. 相似文献

Extending the language of the intuitionistic propositional logic Int with additional logical constants, we construct a wide
family of extensions of Int with the following properties: (a) every member of this family is a maximal conservative extension
of Int; (b) additional constants are independent in each of them.

The aim of this paper is to show that the implicational fragment BKof the intuitionistic propositional calculus (IPC) without
the rules of exchange and contraction has the finite model property with respect to the quasivariety of left residuation algebras
(its equivalent algebraic semantics). It follows that the variety generated by all left residuation algebras is generated
by the finite left residuation algebras. We also establish that BKhas the finite model property with respect to a class of
structures that constitute a Kripke-style relational semantics for it. The results settle a question of Ono and Komori [OK85].

Mathematical modal logic: A view of its evolution 总被引:1,自引:0,他引:1
This is a survey of the origins of mathematical interpretations of modal logics, and their development over the last century or so. It focuses on the interconnections between algebraic semantics using Boolean algebras with operators and relational semantics using structures often called Kripke models. It reviews the ideas of a number of people who independently contributed to the emergence of relational semantics, and compares them with the work of Kripke. It concludes with an account of several applications of modal model theory to mathematics and theoretical computer science. 相似文献

We show the completeness of a Hilbert-style system LK defined by M. Valiev involving the knowledge operator K dedicated to the reasoning with incomplete information. The completeness proof uses a variant of Makinson's canonical model construction. Furthermore we prove that the theoremhood problem for LK is co-NP-complete, using techniques similar to those used to prove that the satisfiability problem for propositional S5 is NP-complete. 相似文献
