On a symbolic method for neutral functional-differential equations with proportional delays
Abstract In this paper, we present a new symbolic method for solving neutral functional-differential equations with proportional delays having variable coefficients via homotopy perturbation method. The proposed symbolic method is also applicable to solve the multi-pantograph equations with variable coefficients. Several numerical examples are given to illustrate the proposed method and the results show that the proposed symbolic method is very effective.
