摘要

设[公式:见文]表示[公式:见文]沿[公式:见文]一般线条和[公式:见文]一般点的放大。在本文中，我们关注[公式:见文]-[公式:见文]上非常多的行束，并研究它们的Seshadri常数与[公式:见文]上的一些限制。此外，我们计算了[公式:见文]的[公式:见文]的nef锥，并研究了其上一些示例线束的Seshadri常数。我们还在[公式:见文][公式:见文][公式:见文]和[公式:见文][公式:见文]上考察了一些示例线束的Seshadri常数。

Seshadri constants on some blow UPS of Projective Spaces

Let [Formula: see text] denote the blow-up of [Formula: see text] along [Formula: see text] general lines and [Formula: see text] general points. In this paper, we focus on [Formula: see text]-very ample line bundles on [Formula: see text] and investigate their Seshadri constants with some restrictions on [Formula: see text]. Additionally, we compute the nef cone of [Formula: see text] for [Formula: see text] and study the Seshadri constants of some ample line bundles on it. We also examine the Seshadri constants of some ample line bundles on [Formula: see text] [Formula: see text] and [Formula: see text] [Formula: see text].

期刊介绍： The International Journal of Mathematics publishes original papers in mathematics in general, but giving a preference to those in the areas of mathematics represented by the editorial board. The journal has been published monthly except in June and December to bring out new results without delay. Occasionally, expository papers of exceptional value may also be published. The first issue appeared in March 1990.
