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 αΈ‘ be another metric with scalar curvature ΞΊ, such that αΈ‘ g on 2-vectors. We show that ΞΊ ΞΊ everywhere on M implies ΞΊ = ΞΊ. Under an additional conditio
