摘要翻译:
我们改进了Hwang,Keum和Szemberg,Tutaj-Gasinska的结果,这些结果将曲面上大量线束的局部不变量Seshadri常数与全局几何纤维结构联系起来。我们证明,当观察在给定曲面的任何有限子集上测量的Seshadri常数时,也会出现同样的图像。

英文摘要:
We refine results of Hwang, Keum and Szemberg, Tutaj-Gasinska which relate local invariants - Seshadri constants - of ample line bundles on surfaces to the global geometry - fibration structure. We show that the same picture emerges when looking at Seshadri constants measured at any finite subset of the given surface.
