M_{0,n}的GIT紧化和翻转

GIT Compactifications of M_{0,n} and Flips

Noah Giansiracusa, David Jensen, Han-Bom Moon

摘要:

我们利用几何不变理论(GIT)构造了模空间M_{0,n}的一大类紧化.这些紧化包括许多以前已知的例子,以及许多新的。由于我们的GIT方法,我们表现出明确的翻转和这些空间之间的除法收缩。

英文摘要:

We use geometric invariant theory (GIT) to construct a large class of compactifications of the moduli space M_{0,n}. These compactifications include many previously known examples, as well as many new ones. As a consequence of our GIT approach, we exhibit explicit flips and divisorial contractions between these spaces.
