Components with the expected codimension in the moduli scheme of stable spin curves

Edoardo Ballico

Abstract


Here we study the Brill–Noether theory of “extremal” Cornalba’s theta-characteristics on stable curves C of genus g, where “extremal” means that they are line bundles on a quasi-stable model of C with #(Sing(C)) exceptional components.

Keywords


Stable curve; theta-characteristic; spin curve; Brill–Noether theory
