摘要：
Our aim in this paper is to investigate the existence and uniqueness of the positive solutions and the asymptotic behavior of the equilibrium points of the fuzzy difference equation x (n+1) = Ax(n-1)x(n-2)/D + Bx(n-3) + Cx(n-4), n = 0, 1, 2, ... , where x n is a sequence of positive fuzzy numbers, the parameters A, B, C, D and the initial conditions x(-4), x(-3), x(-2), x(-1), x(0) are positive fuzzy numbers. Moreover, some numerical examples to the difference system are given to verify our theoretical results. (C) 2017 All rights reserved.
