Nef adelic因子的一个数值刻画

A numerical characterization of nef adelic divisors

Hideaki Ikoma

摘要:

对于一个一般的大阿德尔因子,我们可以联想到一个算术奥肯科夫体,它是一对几何奥肯科夫体和格林函数的凹变换。本文证明了当除数为垂直nef时,凹变换的下确界由绝对极小值给出。这是Moriwaki(在曲线情况下)和Burgos Gil-Moriwaki-Philippon-Sombra(在复曲面情况下)结果的部分推广。

英文摘要:

To a generically big adelic divisor, we can associate an arithmetic Okounkov body, which is a pair of the geometric Okounkov body and the concave transform of the Green functions. In this paper, we show that the infimum of the concave transform is given by the absolute minimum provided that the divisor is vertically nef. This is a partial generalization of results of Moriwaki (in the curve case) and of Burgos Gil-Moriwaki-Philippon-Sombra (in the toric case).
