Abstract

We study the syzygies of canonical curves of genus g3g\geq 3 over an algebraically closed field F\mathbb{F} of characteristic p>0p>0. We provide a new proof of generic Green's Conjecture for pg+42p\geq\frac{g+4}{2}. Using the techniques from the even-genus case, we establish a significant case of the Geometric Syzygy Conjecture for the last syzygy space of a general even-genus canonical curve (assuming p>gp>g). In characteristic 0, it was shown in prior work that this case implies the full conjecture.
