在Del Pezzo表面上计算Zebraki室

Counting Zariski chambers on Del Pezzo surfaces

Thomas Bauer, Michael Funke, Sebastian Neumann

摘要:

Zagliki室提供了一个自然的分解大锥的代数曲面到合理的局部多面体的子锥是有趣的,从点的线性级数。在本文中,我们提出了一种算法,允许有效地确定Zagliki室时,表面上的负曲线是已知的。我们展示了如何可以使用该算法来计算Del Pezzo表面上的腔室的数量。

英文摘要:

Zariski chambers provide a natural decomposition of the big cone of an algebraic surface into rational locally polyhedral subcones that are interesting from the point of view of linear series. In the present paper we present an algorithm that allows to effectively determine Zariski chambers when the negative curves on the surface are known. We show how the algorithm can be used to compute the number of chambers on Del Pezzo surfaces.
