Abstract
We construct a smooth Deligne–Mumford compactification for the moduli space of curves with an m-tuple of spin structures using line bundles on quasi-stable curves as limiting objects, as opposed to line bundles on stacky curves. For all m, we give a combinatorial description of the local structure of the corresponding coarse moduli spaces. We also classify all irreducible and connected components of the resulting moduli spaces of multiple-spin curves.

N1 - Funding Information: It is my pleasure to thank my adviser Gavril Farkas for generously sharing his insight into research as well as giving me financial and academic support during the course of my PhD. I would like to thank my co-adviser Gerard van der Geer for numerous discussions during my stay in Amsterdam. In addition, thanks to Lenny Taelman and David Holmes for providing helpful suggestions at key moments. Special thanks go to Fabio Tonini for helping me with stacks and to Klaus Altmann for helping me extend my scholarship. Finally, I thank Özde Bayer Sertöz for the help with the picture. This research constitutes a chapter in my PhD thesis. My PhD was funded by the Berlin Mathematical School and Graduiertenkolleg 1800 of the Deutsche Forschungsgemeinschaft. I am grateful to the referee for their careful reading and insightful comments.
