In this thesis, we first give a characterization of fixed fields under subgroups of the decomposition group $\mathcal{A}(P_\infty)$ of the Deligne--Lusztig function fields. More specifically, we give a characterization of subgroups in the decomposition group by means of a necessary and sufficient c...
