Koszul上同调及其对模的应用

Koszul cohomology and applications to moduli

Marian Aprodu, Gavril Farkas

摘要:

本文讨论了曲线的合势的最新进展,包括Green猜想和Gonality猜想的证明以及Koszul圈在研究曲线的各种模空间的双有理几何中的应用。我们证明了一些新的结果,包括一个完整的解决方案,任意六边形曲线的格林猜想。最后,我们提出了几个新的syzygies,包括一个Prym-Green猜想的l-根的平凡丛,以及一个强极大秩猜想一般曲线。出现在克莱数学研究所的论文集上。

英文摘要:

We discuss recent progress on syzygies of curves, including proofs of Green's and Gonality Conjectures as well as applications of Koszul cycles to the study of the birational geometry of various moduli spaces of curves. We prove a number of new results, including a complete solution to Green's Conjecture for arbitrary hexagonal curves. Finally, we propose several new conjectures on syzygies, including a Prym-Green conjecture for l-roots of trivial bundles as well as a strong Maximal Rank Conjecture for generic curves. To appear in the Proceedings of Clay Mathematical Institute.
