论文摘要
正常模式与电势在双曲线平衡处的二次近似密切相关。在这里,我们将概念扩展到临界点上电势扩展的情况下,并表明这种扩展具有标准正常模式的某些属性。详细考虑了一些对称示例。
Normal modes are intimately related to the quadratic approximation of a potential at its hyperbolic equilibria. Here we extend the notion to the case where the Taylor expansion for the potential at a critical point starts with higher order terms, and show that such an extension shares some of the properties of standard normal modes. Some symmetric examples are considered in detail.
