Abstract:

Let $F$ be a global field, let $G$ be an unramified quasi-split reductive group over $F$, and let $\chi$ be an everywhere unramified automorphic character of a maximal maximally split torus of $G$. Using Langlands-Shahidi theory, we compute the meromorphic function defined by the action of a global standard intertwining operator associated to $\chi$ on a spherical vector and show that the ratio of its poles in the positive Weyl chamber is well behaved.
