### Compact simple simply connected algebraic groups over $Q_p$ or other local non-archimedean fields

My motivation is to understand the following situation: Given absolutely and almost simple algebraic group $G$ defined over a number field $k$ and a finite valuation $v$ on $k$, when $G(k_v)$ can be ...
