Semi-simple groups that are quasi-split over a tamely-ramified extension Gille, Philippe


Let $K$ be a discretly henselian field whose residue field is separably closed. Answering a question raised by G. Prasad, we show that a semisimple $K$-group $G$ is quasi-split if and only if it quasiâ splits after a finite tamely ramified extension of $K$.
