Abstract

omotopy analysis method (HAM) is a promising method for handling func-
tional equations. Recent publications proved the e ectiveness of HAM in solving
wide variety of problems in di erent elds. HAM has a unique property which
makes it superior to other analytic methods, this property is its ability to con-
trol the convergence region of the solution series. In this work, we clari ed the
advantages and e ects of convergence-control parameter through an example.
