Losev-Manin模空间对经典根系的推广

On generalisations of Losev-Manin moduli spaces for classical root systems

Victor Batyrev, Mark Blume

摘要:

Losev和Manin介绍了稳定的$n$ -点链射影线的精细模空间$\bar{L}_n$。模空间$\bar{L}_{n+1}$同构于与根系$A_n$相关联的复曲面簇$X(A_n)$,这是将秩为$n$的根系$R$与$n$维光滑投射复曲面簇$X(R)$相关联的一般构造的一部分.本文研究了Losev-Manin模空间对其它经典根系族的推广。

英文摘要:

Losev and Manin introduced fine moduli spaces $\bar{L}_n$ of stable $n$-pointed chains of projective lines. The moduli space $\bar{L}_{n+1}$ is isomorphic to the toric variety $X(A_n)$ associated with the root system $A_n$, which is part of a general construction to associate with a root system $R$ of rank $n$ an $n$-dimensional smooth projective toric variety $X(R)$. In this paper we investigate generalisations of the Losev-Manin moduli spaces for the other families of classical root systems.
