摘要:
本文讨论了同伦微扰方法在求解各向同性球对称系统的Tolman-Oppenheimer-Schmidoff方程的非线性质量微分方程中的应用。我们表明,一个得到相同的结果,更容易和直接,通过教科书的幂级数方法。
英文摘要:
In this comment we discuss the application of homotopy perturbation method to a nonlinear differential mass equation that solves the Tolman-Oppenheimer-Volkoff equation for an isotropic and spherically symmetric system. We show that one obtains the same results, more easily and straightforwardly, by means of a textbook power-series method.
