摘要：

The homotopy perturbation technique does not depend upon a small parameter in the equation. By the homotopy technique in topology, a homotopy is constructed with an imbedding parameter p epsilon [0, 1], which is considered as a "smalI parameter". Some examples are given. The approximations obtained by the proposed method are uniformly valid not only for small parameters, but also for very large parameters. (C) 1999 Elsevier Science S.A. All rights reserved.
