Extreme Divisors on ${\bar{M}}_{0,7}$ and Differences over Characteristic 2

Mathieu Dutour Sikirić, Eric Jovinelly

We find 101,052 new extreme divisors on ${\bar{M}}_{0,7}$ (in 31 $S_7$-orbits) and millions of extreme nef curves over characteristic 0. Over characteristic 2, we identify two more $…
