Combinatorial properties of stable spin curves
Lucia Caporaso, Cinzia Casagrande
The geometry of the moduli space of stable spin curves is studied, with emphasis on its combinatorial properties. In this context, the standard graph theoretic framework is not jus…

Characterizing Curves by their odd Theta-characteristics
Lucia Caporaso, Edoardo Sernesi
We show that a general canonical curve is uniquely determined by the finite set of hyperplanes cutting theta-characteristics on it. Geometrical and combinatorial properties of the…
