Pryms of non-cyclic triple coverings and log canonical models of the spin moduli space of genus 2
We show that the moduli spaces of non-triple cyclic coverings of genus 2
curves and that of even spin curves of genus 2 are birationally isomorphic via
the Prym map. We describe the log canonical models of the moduli space of even
spin curves of genus 2 and use this to extend the above birational map.Comment: 24 pages, 1 figur
