线丛的逐次极小

Successive minima of line bundles

Florin Ambro, Atsushi Ito

摘要:

引入并研究了真代数簇上线丛的连续极小。第一个(resp)最后)最小值是宽度(相应地,Seshadri常数)的线丛在非常一般的点。线丛的体积等于连续最小值的乘积。对于复曲面簇上的线丛,其连续极小值等价于矩多面体之差的通常连续极小值的(倒数)。

英文摘要:

We introduce and study the successive minima of line bundles on proper algebraic varieties. The first (resp. last) minima are the width (resp. Seshadri constant) of the line bundle at very general points. The volume of the line bundle is equivalent to the product of the successive minima. For line bundles on toric varieties, the successive minima are equivalent to the (reciprocal of) usual successive minima of the difference of the moment polytope.
