Non-existence of non-trivial normal elements in the Iwasawa Algebra of Chevalley groups

Dong Han, Jishnu Ray, Feng Wei

For a prime $p>2$, let $G$ be a semi-simple, simply connected, split Chevalley group over ${\mathbb{Z}}_p$, $G(1)$ be the first congruence kernel of $G$ and ${\Omega }_{G(1)}$ be the mod-$p$…
