Subconvexity Problem on $\operatorname{GL}_3$ over number fields: the twist aspect

Abstract: Let $F$ denote a number field and let $\mathfrak{q}\subset O_F$ traverse a sequence of prime ideals with norm $N(\mathfrak{q}) \to \infty$ and for each $\mathfrak{q}$, let $$χ\in \widehat{F^{{\times}\setminus} \mathbb{A}<sup>\times}$$ be a finite order character of conductor $\mathfrak{q}$. For a fixed unitary cuspidal automorphic representation $π$ of $\operatorname{GL}_3/F$ we show that \begin{equation*} L(π\otimes χ,\tfrac{1}{2})\ll \ N(\mathfrak{q})^{3/4-κ}.\end{equation*} holds for all $κ&lt; \frac{1}{36}$.
