旗流形的悬挂分裂与自映射
Suspension splittings and self-maps of flag manifolds
摘要:
若$G$是紧连通李群,$T$是极大环面,通过确定上同调幂等元族,给出了$ΣG/T$的楔形分解.这是用来给新的信息的自映射的$G/T$。
英文摘要:
If $G$ is a compact connected Lie group and $T$ is a maximal torus, we give a wedge decomposition of $ΣG/T$ by identifying families of idempotents in cohomology. This is used to give new information on the self-maps of $G/T$.
