“…Therefore, many different methods are used to obtain the solution of the linear and nonlinear IDEs such as the successive approximations, Adomian decomposition, Homotopy perturbation method, Chebyshev and Taylor collocation, Haar Wavelet, Tau and Walsh series methods. [1][2][3][4][8][9][10][11][12][13][14][15][16] . In this study, by means of the homotopy analysis method (HAM), presented by Liao [5][6][7] , a general analytic approach is presented to obtain series solutions of linear IDEs:…”
