The Optimal Homotopy Asymptotic Method with Application to Second Kind of Nonlinear Volterra Integral Equations

International Journal of Analysis and Applications, 2020
In this paper, we solved some problems of nonlinear second kind of Volterra integral equations by Optimal Homotopy Asymptotic Method(OHAM). We compared the results obtained by OHAM with the exact solutions of the problems.
