Abstract: In this paper, we propose a successive approximation method based on fuzzy wavelet like operator for the approximate solution of nonlinear Hammerstein fuzzy integral equations (NHFIE). For this purpose, the convergence conditions and an error estimate are given. Finally, to show the efficiency of presented method, some test problems, for which the exact solution is known, are considered.
