Abstract: The article is concerned with large time behavior of solution to second-order fractal difference equation with positive fuzzy parameters xn+1=A+xnB+xn-1,  n=1,2,⋯, here the initial values xi (i = -1, 0) and the parameters A, B are positive fuzzy numbers. Utilizing a generalization of division (g-division) of fuzzy numbers, one presents large time behaviors of positive fuzzy solution including persistence, boundedness, global convergence. Moreover, two numerical examples verify the effectiveness of the qualitative analysis.

Keywords: Second- order fractal difference equation, g-division, large time behavior, positive fuzzy parameter
