A remark on the rational cohomology of $$\bar S_{1,n} $$
Tóm tắt
We focus on the rational cohomology of Cornalba’s moduli space of spin curves of genus 1 withn marked points. In particular, we show that both its first and its third cohomology group vanish and the second cohomology group is generated by boundary classes.
