摘要

在本文中，我们致力于阿贝尔曲面和双椭圆曲面上的Seshadri常数的研究。我们特别关注所有这些曲面上的边界，仅依赖于所考虑的充足线束的自交。我们的结果改进了先前的边界，并提供了有理数作为边界，这是潜在的Seshadri常数。

Seshadri constants on abelian and bielliptic surfaces–Potential values and lower bounds

In this note we contribute to the study of Seshadri constants on abelian and bielliptic surfaces. We specifically focus on bounds that hold on all such surfaces, depending only on the self-intersection of the ample line bundle under consideration. Our result improves previous bounds and it provides rational numbers as bounds, which are potential Seshadri constants.
