Jorge Rodríguez Contreras, Alberto Reyes Linero, Bladimir Blanco Montes, Primitivo B. Acosta-Humánez

摘要:

本文对含有多参数族的二次系统进行了分析,首先对二次系统进行了识别和分类,以便于研究,然后讨论了有限平面上临界点的稳定性,它的分支,稳定流形,最后讨论了无限平面上临界点的稳定性,然后绘制这些族的分析所得的相图。为了正确地进行这项研究,有必要使用非线性系理论的一些结果,为此,重要的定义和定理,因为它们的重要性,在研究过程中的多参数家庭。代数方面也包括在内。

英文摘要:

This article reveals an analysis of the quadratic systems that hold multiparametric families therefore, in the first instance the quadratic systems are identified and classified in order to facilitate their study and then the stability of the critical points in the finite plane, its bifurcations, stable manifold and lastly, the stability of the critical points in the infinite plane, afterwards the phase portraits resulting from the analysis of these families are graphed. To properly perform this study it was necessary to use some results of the non-linear systems theory, for this reason vital definitions and theorems were included because of their importance during the study of the multiparametric families. Algebraic aspects are also included.
