Notes on the homotopy analysis method: some definitions and theorems. (English)
[J] Commun. Nonlinear Sci. Numer. Simul. 14, No. 4, 983-997 (2009). ISSN 1007-5704

Summary: We describe, very briefly, the basic ideas and current developments of the homotopy analysis method, an analytic approach to get convergent series solutions of strongly nonlinear problems, which recently attracts interests of more and more researchers. Definitions of some new concepts such as the homotopy-derivative, the convergence-control parameter and so on, are given to redescribe the method more rigorously. Some lemmas and theorems about the homotopy-derivative and the deformation equation are proved. Besides, a few open questions are discussed, and a hypothesis is put forward for future studies.
