A Single Proof of Classical Behaviour in Da Costa's Cn Systems
نویسندگان
چکیده
A strong negation in da Costa’s Cn systems can be naturally extended from the strong negation (¬∗) of C1. In [1] Newton da Costa proved the conectives {→, ∧, ∨, ¬∗} in C1 satisfy all schemas and inference rules of classical logic. In the following paper we present a proof that all logics in the Cn herarchy also behave classically as C1. This result tell us the existance of a common property among the paraconsistent family of logics created by da Costa.

Behavioral algebraization of da Costa's C-systems
It is well-known that da Costa’s C-systems of paraconsistent logic do not admit a Blok-Pigozzi algebraization. Still, an algebraic flavored semantics for them has been proposed in the literature, namely using the class of so-called da Costa algebras. However, the precise connection between these semantic structures and the C-systems was never established at the light of the theory of algebraiza...
متن کاملShortcut Node Classification for Membrane Residue Curve Maps
comNode classification within Membrane Residue Curves (M-RCMs) currently hinges on Lyapunov’s Theorem and therefore the computation of mathematically complex eigenvalues. This paper presents an alternative criterion for the classification of nodes within M-RCMs based on the total membrane flux at node compositions. This paper demonstrates that for a system exhibiting simple permeation behaviour...
متن کاملA Single Machine Capacitated Production Planning Problem Under Uncertainty: A Grey Linear Programming Approach
The production planning is an important problem in most of manufacturing systems in practice. Unlike many researches existing in literature, this problem encounters with great uncertainties in parameters and input data. In this paper, a single machine capacitated production planning problem is considered and a linear programming formulation is presented. The production costs are assumed to be u...
متن کاملMass Participation Factor in Defining Non-classical Range of Behavior for Mass Isolated Systems
The new techniques in seismic design of structures are usually attributed to high damping ratios. In such systems, the assumption of classical (i.e. proportional) damping is not valid and in most cases they should be considered as Non-classical systems. Since the analytical tools for studying the behavior of such structures are not easily available, the present work attempts to find the limits,...
