This paper approaches the problem of analyzing the bifurcation phenomena in three-dimensional discontinuous maps, using a piecewise linear approximation in the neighborhood of a border. The existence conditions of periodic orbits are analytically calculated and bifurcations of different periodic orbits are illustrated through numerical simulations. We have illustrated the peculiar features of discontinuous bifurcations involving a stable fixed point, a period-2 cycle, a saddle fixed point, etc. The occurrence of multiple attractor bifurcation and hyperchaos are also demonstrated.
本文采用在边界邻域的分段线性近似方法,研究三维不连续映射中的分岔现象问题。通过解析计算得出周期轨道的存在条件,并通过数值模拟展示不同周期轨道的分岔情况。我们阐述了涉及稳定不动点、周期2循环、鞍点不动点等不连续分岔的独特特征。还证明了多重吸引子分岔和超混沌的出现。
