Hermitian Structures on Twistor Spaces
Annals of Global Analysis and Geometry, 1998Let \((M,g)\) be an oriented self-dual compact Einstein 4-manifold \((M,g)\) and \(Z\) its twistor space with the standard Riemannian metric \(h_t\) which depends on the parameter \(t>0\). It is well-known that \(Z\) admits a canonical complex structure \(J_Z\) which is orthogonal with respect to any standard metric \(h_t\), \(t>0\).

Let (M,\(\omega)\) be an almost symplectic manifold and \({\mathcal T}(M,\omega)\) its symplectic twistor space, i.e. the bundle of the compatible complex structures of its tangent spaces, as considered by \textit{M. Dubois-Violette} [Mathématique et physique, Sémin. Éc. Norm. Supér., Paris 1979-1982, Prog. Math.

TWISTOR SPACES AND FANO THREEFOLDS
The Quarterly Journal of Mathematics, 1994Usually, twistor spaces are certain complex 3--manifolds fibred over a Riemannian 4-manifold. It was shown by \textit{N. J. Hitchin} [Proc. Lond. Math. Soc., III. Ser. 43, 133-150 (1981; Zbl 0474.14024)] and by \textit{Th. Friedrich} and \textit{H. Kurke} [Math. Nachr.
