摘要
引入复仿射不变量及旋转不变量概念,得到二维映射在共振与非共振情形下规范型系数的代数结构,并利用规范型讨论二维映射的多重Hopf分支.
The algebraic structures of coefficients in normal forms of two-dimensional maps in resonance and non-resonance cases are obtained by introducing the invariant under complex affine transformation and the invariant under rotational transformation.The multiple Hopf bifurcations are discussed.
