Predicate modal logics based on Kwith non-compact extra axioms are discussed and a sufficient condition for the model existence theorem is presented. We deal with various axioms in a general way by an algebraic method, instead of discussing concrete non-compact axioms one by one. 相似文献

By supplying propositional calculus with a probability semantics we showed, in our 1996, that finite stochastic problems can be treated by logic-theoretic means equally as well as by the usual set-theoretic ones. In the present paper we continue the investigation to further the use of logical notions in probability theory. It is shown that quantifier logic, when supplied with a probability semantics, is capable of treating stochastic problems involving countably many trials. 相似文献

This paper deals with modal Horn formulas. It contains a characterization of the classes of models definable by modal universal
Horn formulas as well as a preservation result for modal universal Horn formulas.

This is a purely conceptual paper. It aims at presenting and putting into perspective the idea of a proof-theoretic semantics
of the logical operations. The first section briefly surveys various semantic paradigms, and Section 2 focuses on one particular
paradigm, namely the proof-theoretic semantics of the logical operations.

A formal logical system for sortal quantifiers, sortal identity and (second order) quantification over sortal concepts is formulated. The absolute consistency of the system is proved. A completeness proof for the system is also constructed. This proof is relative to a concept of logical validity provided by a semantics, which assumes as its philosophical background an approach to sortals from a modern form of conceptualism. 相似文献
