The local form and the holonomy of a pseudo-Kähler manifold admitting such a structure are obtained, leading to a possible complex generalization of homogeneous plane waves. The same question is tackled in the case of pseudo-hyper-Kähler and pseudo-quaternion Kähler manifolds.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0393044013000995#http://www.sciencedirect.com/restricted access515.122.4Homogeneous plane wavesPseudo-hyper-KählerPseudo-KählerPseudo-quaternion KählerReductive homogeneous pseudo-Riemannian spacesGeometría diferencialTopología1204.04 Geometría Diferencial1210 Topología
