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

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.
