The Riemannian constant holomorphic sectional curvature conjecture for compact Hermitian manifolds

Let (Mn,g)(M^n,g) be a compact Hermitian manifold of complex dimension n2n\geq 2, and let HrH^r denote the Riemannian holomorphic sectional curvature, with RrR^r the curvature of the Riemannian connection. Riemannian constant holomorphic sectional curvature conjecture. If

Hr=cH^r=c

is constant, then gg must be Kähler when c0c\neq 0, and gg must be Riemannian flat, namely Rr=0R^r=0, when c=0c=0. This is the Riemannian twin of the Chern-connection conjecture. Its resolution status is not specified in the supplied text.
