چکیده
Here we consider degenerations of stable spin curves for a fixed smoothing of a non-stable curve: we are able to give enumerative results and a description of limits of stable spin curves. We give a geometrically meaningful definition of spin curves over non-stable curves.

Spin Structures over Non Stable Curves
Here we consider degenerations of stable spin structures when a smoothing of a non stable curve is fixed. We are able to give enumerative results and a geometric description of spin structures over non stable curves using twisted spin curves.
متن کاملModuli of Twisted Spin Curves
In this note we give a new, natural construction of a compactification of the stack of smooth r-spin curves, which we call the stack of stable twisted r-spin curves. This stack is identified with a special case of a stack of twisted stable maps of Abramovich and Vistoli. Realizations in terms of admissible Gm-spaces and Q-line bundles are given as well. The infinitesimal structure of this stack...
متن کاملCombinatorial properties of stable spin curves
The first part of this paper describes the moduli space of stable spin curves (constructed in [Cor89]), explaining how its geometry is governed by the combinatorics of stable curves. In this context, the standard graph theoretic framework (where to every stable curve one associates its “dual graph”) is not just a book-keeping device: in Section 2, some purely combinatorial results are proved (T...
متن کاملEnriched Spin Curves on Stable Curves with Two Components
In [M], Mainò constructed a moduli space for enriched stable curves, by blowing-up the moduli space of Deligne-Mumford stable curves. We introduce enriched spin curves, showing that a parameter space for these objects is obtained by blowing-up the moduli space of spin curves.
متن کاملStable twisted curves and their r-spin structures
The object of this paper is the notion of r-spin structure: a line bundle whose rth power is isomorphic to the canonical bundle. Over the moduli functor Mg of smooth genus-g curves, r-spin structures form a finite torsor under the group of r-torsion line bundles. Over the moduli functor Mg of stable curves, r-spin structures form an étale stack, but the finiteness and the torsor structure are l...
