The normal bundle of canonical genus 8 curves

Algebraic Geometry 2017-03-28 v2

Abstract

We study the stability of the normal bundle of canonical genus 88 curves and prove that on a general curve the bundle is stable. The proof rests on Mukai's description of these curves as linear sections of a Grassmannian G(2,6)\mathrm{G}(2,6). This is the next case of a conjecture by M. Aprodu, G. Farkas, and A. Ortega: the general canonical curve of every genus g7g \geq 7 should have stable normal bundle. We also give some more evidence for this conjecture in higher genus.
