复曲面向量丛的模

Moduli of toric vector bundles

Sam Payne

摘要:

给出了具有固定等变全陈类的环面向量丛的模栈作为框架丛的细模概型在线性群作用下的商.这种精细模方案被明确地描述为局部闭子概形的产品的部分标志品种削减组合指定的秩条件。我们使用这种描述表明,模的秩三环面向量丛满足墨菲定律,在Vakil的意义。初步部分的文件给一个自我包含的介绍Klyachko的分类复曲面向量丛。

英文摘要:

We give a presentation of the moduli stack of toric vector bundles with fixed equivariant total Chern class as a quotient of a fine moduli scheme of framed bundles by a linear group action. This fine moduli scheme is described explicitly as a locally closed subscheme of a product of partial flag varieties cut out by combinatorially specified rank conditions. We use this description to show that the moduli of rank three toric vector bundles satisfy Murphy's Law, in the sense of Vakil. The preliminary sections of the paper give a self-contained introduction to Klyachko's classification of toric vector bundles.
