On the weight zero compactly supported cohomology of ${\mathcal{H}}_{g,n}$

Madeline Brandt, Melody Chan, Siddarth Kannan

For $g\ge 2$ and $n\ge 0$, let ${\mathcal{H}}_{g,n}\subset {\mathcal{M}}_{g,n}$ denote the complex moduli stack of $n$-marked smooth hyperelliptic curves of genus $g$. A normal crossin…
