论文摘要
我们与多项式的三维刚性差异系统一起工作。使用Lyapunov常数，我们获得了在其中心歧管上已知刚性中心的循环性的下限。此外，我们获得了一个二次刚性中心的示例，可以从中分叉13个限制循环，这是三维二次系统的新下限。
We work with polynomial three-dimensional rigid differential systems. Using the Lyapunov constants, we obtain lower bounds for the cyclicity of the known rigid centers on their center manifolds. Moreover, we obtain an example of a quadratic rigid center from which is possible to bifurcate 13 limit cycles, which is a new lower bound for three-dimensional quadratic systems.
