In this work we introduce the notion of fuzzy volterra di erence equations and study the dynamical
properties of some classes of this type of equations. We prove some comparison theorems for these
equations in terms of ordinary volterra di erence equations. Using these results the stability of the
fuzzy nonlinear volterra di erence equations is investigated.
