Almost hermitian manifolds and Osserman condition

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2001
The aim of this work is to extend a previous result of \textit{Q.-S. Chi} [J. Differ. Geom. 28, 187-202 (1988; Zbl 0654.53053)] which shows that Osserman Kähler manifolds are complex space forms provided that the holomorphic sectional curvature is nonpositive or nonnegative.

Homogeneous almost quaternion-hermitian manifolds

2012
An almost quaternion-Hermitian structure on a Riemannian manifold (M4n; g) is a reduction of the structure group of M to Sp(n)Sp(1) SO(4n). In this paper we show that a compact simply connected homogeneous almost quaternion-Hermitian manifold of non-vanishing Euler characteristic is either a Wolf space, or S2 S2, or the complex quadric SO(7)=U(3).

ALMOST EINSTEIN-HERMITIAN MANIFOLDS

JP Journal of Geometry and Topology
In this paper, we show that every almost Einstein-Hermitian 4-manifold (i.e., almost Hermitian 4-manifold with -invariant Ricci tensor and harmonic Weyl tensor) is either Einstein or Hermitian. Consequently, we obtain that any almost Einstein-Hermitian 4-manifold which is not Einstein must be Hermitian and that every almost Einstein-Hermitian 4 ...
