摘要
研究了时滞Lolta-Volterra生态模型.利用同伦分析方法,得到了该模型解的近似展开式,并对近似解与数值解进行了比较.比较结果表明,近似解具有较高的精度,该方法用于生态模型研究可行.
Time-delay Lokta-Volterra ecological model was considered. Using the method of homotopy analysis, the approximation of the solution for the model was obtained. And compared to the numerical solution, the approximation solution from the method was agreement well with the numerical solution. It shows the method is feasible to studying Lolta- Volterra ecological model.
