关于光滑射影超曲面的Hodge结构变分的第二基本型的注记

A brief note on the second fundamental form of the variation of Hodge structure of a smooth projective hypersurface

Emmanuel Allaud

摘要:

利用Hodge结构的经典识别和Hodge结构的无穷小变分与光滑射影超曲面的Jacobian理想的作用,确定了光滑射影超曲面的Hodge结构的变分的第二基本型.这种简单的代数描述也意味着,在这种情况下,霍奇结构的变化满足一组新的二阶偏微分方程。

英文摘要:

We determine the second fundamental form of a variation of Hodge Structure of a smooth projective hypersurface using the classical identification of the Hodge structure and the action of the infinitesimal variation of Hodge structure with pieces of the Jacobian Ideal of the hypersurface. This simple algebraic description also implies that, in this case, the variation of Hodge structure satisfies a new set of second order partial differential equations.Comments are welcome!
