摘要:
本文研究实分裂半单李代数的Jacobi元的等谱实流形的拓扑。流形与定义在半单李代数上的广义(非周期)Toda格点方程的紧化水平集有关。然后,我们给出了一个细胞分解和相关的链复形的流形通过引入彩色Dynkin图,其中参数化的细胞在分解。我们还讨论了流形的Morse链复形。
英文摘要:
This paper concerns the topology of isospectral real manifolds of certain Jacobi elements associated with real split semisimple Lie algebras. The manifolds are related to the compactified level sets of the generalized (nonperiodic) Toda lattice equations defined on the semisimple Lie algebras. We then give a cellular decomposition and the associated chain complex of the manifold by introducing colored Dynkin diagrams which parametrize the cells in the decomposition. We also discuss the Morse chain complex of the manifold.
