We endow the quotient manifold with an almost contact metric structure. We use this fact to connect pseudo-Kähler homogeneous structures with almost contact metric homogeneous structures. This relation will have consequences in the class of the almost contact manifold. Indeed, if we choose a pseudo-Kähler homogeneous structure of linear type, then the reduced, almost contact homogeneous structure is of linear type and the reduced manifold is of type C5⊕C6⊕C12 of Chinea-González classification.engAtribución 3.0 Españajournal articlehttps://doi.org/10.3390/axioms9030094open access512Ambrose–Singer connectionsalmost contact metric manifoldshomogeneous manifoldshomogeneous structurespseudo-Kähler manifoldspseudo-Riemannian metricÁlgebra1201 Álgebra
