The Euler characteristic of local systems on the moduli of genus 3 hyperelliptic curves

Gilberto Bini, Gerard van der Geer

For a partition $lambda=\{lambd{a}_1\ge {\lambda }_2\ge {\lambda }_3\}$ of non-negative integers, we calculate the Euler characteristic of the local system $V_{\lambda }$ on the moduli space of genus 3 hy…
