具有非常充分典范除子的正则曲面的无穷小Torelli定理

Infinitesimal Torelli Theorem for regular surfaces with very ample canonical divisor

Igor Reider

摘要:

本文证明了曲面的无穷小Torelli定理,它满足以下条件:1)曲面的典范丛是由它的整体瓣生成的,2)几何亏格$p_g \geq 4$,3)不规则性$q=0$ .主要的新颖性是实现的Kodaira-Spencer类躺在内核的上同调杯产品控制的衍生物的周期图的重量2类的相干层的表面。

英文摘要:

The article proves the Infinitesimal Torelli theorem for surfaces subject to the following conditions: 1) the canonical bundle of a surface is ample and generated by its global sections, 2)the geometric genus $p_g \geq 4$, 3) the irregularity $q=0$ . The main novelty is a realization of the Kodaira-Spencer classes lying in the kernel of the cohomology cup-product controlling the derivative of the period map of weight 2 in the category of the coherent sheaves of a surface.
