Mgnbar.info: two new layers

🫧 Open on Bubbles Back in 2023 , together with Ignacio Barros , I made Mgnbar.info , a website about the geometry of $\overline{\mathrm{M}}_{g,n}$, the moduli space of stable $n$-pointed genus $g$ curves. For a long time it showed a single invariant, the Kodaira dimension. It now has two more layers, which you can pick from the selector above the table, and the Kodaira dimension layer itself has gained some extra information. The tautological ring. For each $(g,n)$ the table records whether the Chow ring of
