论文摘要
非线性标志是嵌套闭合子曼膜的有限序列。我们研究了非线性旗帜的特征歧管的几何形状，以这种方式概括了非线性的司羊grass虫。作为一种应用，我们描述了由嵌套的符号次级亚曼群（即符号非线性非线性标志）组成的哈密顿型差异的一类旋转。
A nonlinear flag is a finite sequence of nested closed submanifolds. We study the geometry of Frechet manifolds of nonlinear flags, in this way generalizing the nonlinear Grassmannians. As an application we describe a class of coadjoint orbits of the group of Hamiltonian diffeomorphisms that consist of nested symplectic submanifolds, i.e., symplectic nonlinear flags.
