From the reviews: "The book is devoted to the presentation of the homotopy analysis method (HAM) applied to the resolution of nonlinear differential equations. ... The book will be useful for researchers or engineers which are faced to the resolution of nonlinear differential equations. Besides the presentation of the HAM, the description of the application of this powerful method to the many examples contained in the book will help them when they will try to apply this tool to their own problems."
