Spectral flow, Llarull's rigidity theorem in odd dimensions and its generalization
收藏 引用
Science China mathematics 2024年 第5期67卷 1103-1114页
作者: Yihan Li Guangxiang Su Xiangsheng Wang chern institute of mathematics&lpmc Nankai UniversityTianjin 300071China School of mathematics Shandong UniversityJinan 250100China
For a compact spin Riemannian manifold(M,g^(TM))of dimension n such that the associated scalar curvature kT M verifies that k^(TM)≥n(n-1),Llarull’s rigidity theorem says that any area-decreasing smooth map f from M ... 详细信息

Global structure of spectra of periodic non-Hermitian Jacobi operators
收藏 引用
Science China mathematics 2024年
作者: Hui Lu Jiangong You School of mathematics Nanjing Audit University chern institute of mathematics and lpmc Nankai University
We give global structure of spectra of periodic non-Hermitian Jacobi operators by the discriminant and its stationary points. We also give necessary and sufficient conditions for real spectra and single interval spectra.

Compatible Lie Bialgebras
收藏 引用
Communications in Theoretical Physics 2015年 第6期63卷 653-664页
作者: 吴明忠 白承铭 chern institute of mathematics & lpmc Nankai University
A compatible Lie algebra is a pair of Lie algebras such that any linear combination of the two Lie brackets is a Lie bracket. We construct a bialgebra theory of compatible Lie Mgebras as an analogue of a piiLie bialge... 详细信息
