TRICHOTOMY, STABILITY, AND OSCILLATION OF A FUZZY DIFFERENCE EQUATION G. STEFANIDOU AND G. PAPASCHINOPOULOS Received 10 November 2003 We study the trichotomy character, the stability, and the oscillatory behavior of the positive solutions of a fuzzy difference equation. 1. Introduction Difference equations have already been successfully applied in a number of sciences (for a detailed study of the theory of difference equations and their applications, see [1, 2, 7, 8, 11]. The problem of identifying, modeling, and solving a nonlinear difference equation concerning a real-world phenomenon from experimental input-output data, which is uncertain, incomplete, imprecise, or vague, has been attracting increasing attention. | TRICHOTOMY STABILITY AND OSCILLATION OF A FUZZY DIFFERENCE EQUATION G.

Introduction Difference equations have already been successfully applied in a number of sciences for a detailed study of the theory of difference equations and their applications see 1 2 7 8 11 . The problem of identifying modeling and solving a nonlinear difference equation concerning a real-world phenomenon from experimental input-output data which is uncertain incomplete imprecise or vague has been attracting increasing attention in recent years. In addition nowadays there is an increasing recognition that for understanding vagueness a fuzzy approach is required. The effect is the introdution and the study of the fuzzy difference equations see 3 4 13 14 15 . In this paper we study the trichotomy character the stability and the oscillatory behavior of the positive solutions of the fuzzy difference equation V 1 k i 1 CiXn-pi xn 1 A X 1 m J Lj l djxn qj where k m e 1 2 . A Ci dj i e 1 2 . k j e 1 2 . m are positive fuzzy numbers pi i e 1 2 . k qj j e 1 2 . m are positive integers such that P1 p2 pk q1 q2 qm and the initial values xi i e n n 1 . 0 where n ma l pk qU are positive fuzzy numbers. Studying a fuzzy difference equation results concerning the behavior of a related family of systems of parametric ordinary difference equations is required.

Preliminaries We need the following definitions. For a set B
