三重或四重光滑Fano运动曲线的圆锥

The cone of moving curves of a smooth Fano three- or fourfold

Sammy Barkowski

摘要:

本文通过给出截锥的若干方程,描述了三重和四重光滑Fano运动曲线的闭锥。这些方程是由除数压缩的例外因子和双有理模型的nef因子通过翻转序列导出的.这篇论文是在Stefan Kebekus的监督下撰写的。

英文摘要:

We describe the closed cone of moving curves of smooth Fano three- and fourfolds by giving finitely many equations that cut out the cone. The equations are induced by the exceptional divisors of divisorial contractions and by nef divisors on birational models obtained by sequences of flips.The results presented here are part of the author's Ph.D. thesis, written under the supervision of Stefan Kebekus.
