We establish extremality of Riemannian metrics g with non-negative curvature operator on symmetric spaces M = G/K of compact type with rk Grk K 1. Let ḡ be another metric with scalar curvature κ, such that ḡ g on 2-vectors. We show that κ κ everywhere on M implies κ = κ. Under an additional conditio
