New Bifurcation Patterns in Elementary Bifurcation Problems With Single-Side Constraint
-
摘要: 含约束分岔是非线性动力系统周期解分岔研究中遇到的普遍问题,然而现有的奇异性理论关于此类问题的结果还很少。作为探讨和补充,给出余维数不大于3的10种基本分岔在约束情况下的转迁集和摄动保持分岔图的计算结果。可为约束分岔问题的研究提供直接利用的结果。Abstract: Bifurcations with constraints are open problems appeared in research on periodic bifurcations of nonlinear dynamical systems,but the present singularity theory doesn't contain any analytical methods and results about it.As the complement to singularity theory and the first step to study on constrained bifurcations,here are given the transition sets and persistent perturbed bifurcation diagrams of 10 elementary bifurcation of codimension no more than three.
