Let $G$ a split connected reductive group and $G(\mathbb{A})$ his points in the ring of adeles.
We have a degree map $G(\mathbb{A})\rightarrow X_{*}(Z)$ where $Z$ is the center of $G$.
Let $G(\mathbb{A})^{1}$ the degree zero elements and take an element $\gamma\in G(\mathbb{A})$
Do we have an isomorphism between $G_{\gamma}(\mathbb{A})^{1}\backslash G(\mathbb{A})^{1}$ and $G_{\gamma}(\mathbb{A})\backslash G(\mathbb{A})$ where $G_{\gamma}$ is the centralizer of $\gamma$?
