摘要:

本文研究了一个含无穷小参数的广义二维三次 Lotka–Volterra 模型。考虑了三种不同情形:一个非退化情形和两个退化情形,并研究了模型在这三种情形下的局部行为。在非退化情形中分别得到六幅分岔图、含三十个不同区域;在两个退化情形中得到十六幅图、含四十个区域。

英文摘要:

A generalized two-dimensional cubic Lotka-Volterra model with infinitesimal parameters is studied. Three different cases have been considered, one non-degenerate and two degenerate. The local behavior of the model has been studied in the three cases. Six bifurcation diagrams with thirty different regions have been obtained in the non-degenerate case, respectively, sixteen diagrams with forty regions in the two degenerate cases.
