Numerical and analytic existence of proposal problem formulation over fuzzy interval

In this paper, we proved the convergence of the solution for the nonlinear fuzzy volterra integral classes equation over fuzzy interval with high computational and complexity to find the solution in analytical method, so we describable this solution by using Homotopy perturbation method, by using Banach fixed point theory for existence and uniqueness. That with explained numerical examples. Finally using the MAPLE program to solve our problem.
