Automorphism Groups of Endomorphisms of ${\mathbb{P}}^1({\bar{\mathbb{F}}}_p)$

Julia Cai, Benjamin Hutz, Leo Mayer +1

For any algebraically closed field $K$ and any endomorphism $f$ of ${\mathbb{P}}^1(K)$ of degree at least 2, the automorphisms of $f$ are the Möbius transformations that commute with…
