An Intuitionistic Logic for Sequential Control

چکیده
We introduce a propositional logic ICL, which adds to intuitionistic logic elements of classical reasoning without collapsing it into classical logic. This logic includes a new constant for false, which augments false in intuitionistic logic and in minimal logic. We define Kripke models for ICL and show how they translate to several other forms of semantics. We define a sequent calculus and prove cut-elimination. We then formulate a natural deduction proof system with a term calculus that gives a direct, computational interpretation of contraction. This calculus shows that ICL is fully capable of typing programming language control operators such as call/cc while maintaining intuitionistic implication as a genuine connective.

AN ALGEBRAIC STRUCTURE FOR INTUITIONISTIC FUZZY LOGIC
In this paper we extend the notion of degrees of membership and non-membership of intuitionistic fuzzy sets to lattices and introduce a residuated lattice with appropriate operations to serve as semantics of intuitionistic fuzzy logic. It would be a step forward to find an algebraic counterpart for intuitionistic fuzzy logic. We give the main properties of the operations defined and prove som...
متن کاملEvaluating Construction Projects by a New Group Decision-Making Model Based on Intuitionistic Fuzzy Logic Concepts
Select an appropriate project is a main key for contractors to increase their profits. In practice, in this area the uncertainty and imprecise of the involved parameters is so high. Therefore, considering fuzzy sets theory to deal with uncertainly is more appreciate. The aim of this paper is present a multi-criteria group decision-making model under an intuitionistic fuzzy set environment. Henc...
متن کاملAn Intuitionistic Epistemic Logic for Sequential Consistency on Shared Memory
In the celebrated Gödel Prize winning papers, Herlihy, Shavit, Saks and Zaharoglou gave topological characterization of waitfree computation. In this paper, we characterize waitfree communication logically. First, we give an intuitionistic epistemic logic K∨ for asynchronous communication. The semantics for the logic K∨ is an abstraction of Herlihy and Shavit’s topological model. In the same wa...
متن کاملIntuitionistic fuzzy logic for adaptive energy efficient routing in mobile ad-hoc networks
In recent years, mobile ad-hoc networks have been used widely due to advances in wireless technology. These networks are formed in any environment that is needed without a fixed infrastructure or centralized management. Mobile ad-hoc networks have some characteristics and advantages such as wireless medium access, multi-hop routing, low cost development, dynamic topology and etc. In these netwo...
متن کاملTruth Values and Connectives in Some Non-Classical Logics
The question as to whether the propositional logic of Heyting, which was a formalization of Brouwer's intuitionistic logic, is finitely many valued or not, was open for a while (the question was asked by Hahn). Kurt Gödel (1932) introduced an infinite decreasing chain of intermediate logics, which are known nowadays as Gödel logics, for showing that the intuitionistic logic is not finitely (man...
