The Chow ring of $S_{5}^{-}$ is tautological

Bogdan Carasca

The moduli spaces $S_{g}^{-}$ parametrise odd spin curves of genus $g$ . These are pairs $[C, I^\cdot]$ where $C$ is a smooth genus $g$ curve of and $I^\cdot$ is a line bundle on $C$ su…

Uniruledness of some moduli spaces of pointed spin curves

Bogdan Carasca

The moduli space $S_{g, 2 n}$ parametrizes pointed curves with spin structure. These are tuples $[C, p_{1}, \dots, p_{2 n}, I^\cdot]$ where $I^\cdot \in Pic (C)$ such that $Î·^{\o…

Non--tautological cycles on Prym moduli spaces

Bogdan Carasca, Riccardo Redigolo

We denote by $R_{g; m}$ the moduli space of $m$ --pointed Prym curves of genus $g$ , that is, tuples $[C / C; x_{1}, \dots, x_{m}]$ where $[C, x_{1}, \dots, x_{m}]$ is an…
