Boğaziçi Üniversitesi UCGEN SeminerleriOn nilpotent automorphism groups of function fields Burçin Güneş We study the automorphisms of a function field of genus $g\geq 2$ over an algebraically closed field of positive characteristic $p$. More precisely, we show that the order of a nilpotent subgroup $G$ of its automorphism group is bounded by $16(g−1)$ when $G$ is not a $p$-group. We show that if $|G|=16(g−1)$, then $g−1$ is a power of $2$. Furthermore, we provide an infinite family of function fields attaining the bound. This is a joint work with Nurdagül Anbar.
