Alex Abreu, Marco Pacini

摘要:

本文证明了$M_{0,n}^{\text{trop}}$和$\overline{M}_{0,n}^{\text{trop}}$的自同构群同构于$n\geq5$的置换群$S_n$,而$M_{0,4}^{\text{trop}}$和$\overline{M}_{0,4}^{\text{trop}}$的自同构群同构于置换群$S_3$ .

英文摘要:

In this paper we show that the automorphism groups of $M_{0,n}^{\text{trop}}$ and $\overline{M}_{0,n}^{\text{trop}}$ are isomorphic to the permutation group $S_n$ for $n\geq5$, while the automorphism groups of $M_{0,4}^{\text{trop}}$ and $\overline{M}_{0,4}^{\text{trop}}$ are isomorphic to the permutation group $S_3$.
