Distribution of limit cycles for a class of higher - degree degenerate planar polynomial systems of codimension two is discussed
摘要討論了一類余維2的高次退化平面多項式系統的極限環分佈，證明了此系統至多存在3個極限環。 -
A group of generators of imga expressed by a base of mo is given. in part two, we discuss the ( z2 ) k - actions with fixed point set of constant codimension and determine the ideal j
將上面結果應用於流形纖維化的研究，得到一組以mo _ *的基表示的imgo _ * ~ k的生成元。 -
The bifurcation analysis of the model depending on all parameter indication that it exhibits numerous kinds of bifurcation phenomena, including the saddle - node bifurcation, the supercritical and subcritical hopf bifurcation, and the lioinoclinic bifurcation. in the generic case, the model has the bifurcation of cusp type ol ' codimension 2 ( i. e. bogdanov - taken bifurcation ) but for some specific parameter values it has a multiple focus of multiplicity at least 2. and, we give the global analysis
本文考慮具非單調功能反應函數的捕食者?食餌系統，討論了系統的bogdanov - taken分支，給出了不同種類的分支現象，包括鞍-結點分支，上臨界與下臨界hopf分支，和同宿軌分支，並討論了無窮遠點的定性分析，給出了全局結構。
