复Grassmann流形$G_{q+1,2}$的泛参数空间

Universal spaces of parameters for complex Grassmann manifolds $G_{q+1,2}$

Nikita Klemyatin

摘要:

Buchstaber和Terzic对流形$M^{2n}$引入了泛参数空间$\mathcal{F}$的概念,它具有紧致环面$T^k$,$k \leq n$的有效作用量,并具有一些附加性质.具有特殊属性。构造因子$M^{2n}/T^k$需要该空间。Buchstaber和Terzic构造了$G_{5,2}$的泛参数空间。本文构造了复Grassmann流形$G_{q+1,2}$的泛参数空间。我们的构造是基于Salamon,McDuff和Hessel的带有$q+1$标记点的亏格为零的稳定曲线的模空间的构造.

英文摘要:

Buchstaber and Terzic introduced a notion of universal space of parameters $\mathcal{F}$ for a manifold $M^{2n}$, which has an effective action of compact torus $T^k$ , $k \leq n$ with some additional properties. with special properties. This space is needed to construction of factor $M^{2n}/T^k$. Buchstaber and Terzic constructed the universal space of parameters for $G_{5,2}$. In this work we construct universal space of parameters for complex Grassmann manifold $G_{q+1,2}$. Our construction is based on the construction of moduli space of stable curves of genus zero with $q+1$ marked points due to Salamon, McDuff and Hofer.
