Abstract:For a prime p > 2, let G be a semi-simple, simply connected, split Chevalley group over Zp, G(1) be the first congruence kernel of G and Ω G(1) be the mod-p Iwasawa algebra defined over the finite field Fp. Ardakov, Wei, Zhang [2] have shown that if p is a "nice prime " (p ≥ 5 and p ∤ n + 1 if the Lie algebra of G( 1) is of type An), then every non-zero normal element in Ω G(1) is a unit. Furthermore, they conjecture in their paper that their nice prime condition is superfluous. The main goal of this article i… Show more
