Hodge丛的Arakelov型不等式

Arakelov-type inequalities for Hodge bundles

Chris Peters

摘要:

在奇异纤维周围的单值性是幂幺的假设下,证明了经典的Arakelov不等式的推广,它适用于亏格$p$上的亏格$g$的曲线族的相对正则丛的次数$d$.这个相对典范丛是Hodge丛的正则扩张,并且将不等式推广到Hodge结构的复变的Hodge丛的度.

英文摘要:

We give a proof of generalizations of the classical Arakelov inequality valid for the degree $d$ of the relative canoincal bundle of a family of curves of genus $g$ over a complete curve of genus $p$ under the assumption that the monodromy around the singular fibers is unipotent. This relative canonical bundle is the (canonical extension of) the Hodge bundle and the inequality is generalized to the degrees of the Hodge bundles of a complex variation of Hodge structures.
