The evolution of positively curved invariant Riemannian metrics on the Wallach spaces under the Ricci flow

N. A. Abiev, Yu. G. Nikonorov

This paper is devoted to the study of the evolution of positively curved metrics on the Wallach spaces $SU(3)/T_{\max }$, $Sp(3)/Sp(1)\times Sp(1)\times Sp(1)$, and $F_4/Spin(8)$. W…
