摘要

探讨了协同投影的概念,证明了两个新的技术成果;首先给出了合集格式的投影的精确刻画,其次证明了Aprodu投影定理的一个逆。应用这些结果,证明了由足够高次线性系统嵌入的一般非极大向性曲线的极值合是由卷形曲线产生的。最后,我们证明了任意次椭圆曲线一般覆盖的格林猜想,并证明了偶格和极大向性曲线的一个新结果。

Projecting syzygies of curves
We explore the concept of projections of syzygies and prove two new technical results; we firstly give a precise characterization of syzygy schemes in terms of their projections, secondly, we prove a converse to Aprodu's Projection Theorem. Applying these results, we prove that extremal syzygies of general curves of non-maximal gonality embedded by a linear system of sufficiently high degree arise from scrolls. Lastly, we prove Green's Conjecture for general covers of elliptic curves (of arbitrary degree) as well as proving a new result for curves of even genus and maximal gonality.
