The isomorphism types of parabolic subgroups in Kac-Moody groups
Zhao Xu-an, Ruan Yangyang, Wang Ran
In this paper we discuss the isomorphism types of parabolic subgroups in Kac-Moody groups. The results have applications in the study of topology of Kac-Moody groups and their clas…
Differential geometry of general affine plane curves
Zhao Xu-an, Gao Hongzhu
In this paper we study the general affine geometry of curves in affine space . For a regular plane curves we define two kinds of moving frames. The first is of minimal order i…
Poincaré series and rational cohomology rings of Kac-Moody groups and their flag manifolds
Zhao Xu-an, Jin Chunhua, Zhang Jimin
In this paper, we study the rational cohomology rings of indefinite Kac-Moody groups and their flag manifolds. By extracting the information of cohomology from the Poincaré series,…
On the Poincaré series of Kac-Moody Lie algebras
Jin chunhua, Zhao Xu-an
In this paper, we discuss the Poincaré series of Kac-Moody Lie algebras, especially for indefinite type. Firstly, we compute the Poincaré series of certain indefinite Kac-Moody Lie…
