$E_8$, the most exceptional group

The five exceptional simple Lie algebras over the complex number are included one within the other as $G_2 \subset F_4 \subset E_6 \subset E_7 \subset E_8$. The biggest one, $E_8$, is in many ways

Geometric flow and rigidity on symmetric spaces of noncompact type

In this paper we show that, under a suitable condition, every nonsingular geometric flow on a manifold which is modeled on the Furstenberg boundary of X, where X is a symmetric space of non-compact
