The Homotopy perturbation method is amongst very useful techniques for solving functional equations, several types of nonlinear equations, integral equations.... The convergence control parameters may determine the conditions for convergence of the method.

Article On the convergence of Homotopy perturbation method

Dear respected Doctor Sina Etemad

Thank you very much for your informations concerning the convergence of Homotopy Perturbation method

We have homotopy analysis method which depends on the convergence parameter h. For HAM I have some papers to find the optimal h.

Also I have a joint paper with prof. He to apply the CESTAC method to find the optimal iteration, approximation and error of the HPM.

thank you very much for your valuable information, and I would be grateful if you would provide me with some articles related to the topic of convergence of HPM Best regards,

Prof. Dr. Bashir Kharrat
