✦ Synopsis
We study a class of compact complex manifolds, with positive first Chern class, fibered over products of projective spaces. We prove that these bundles carry Einstein-Kähler metrics when the projective spaces of the basis have the same dimension. When this dimensional condition is not satisfied, we estimate their Ricci tensor in another paper.

For a homogeneous space G/P , where P is a parabolic subgroup of a complex semisimple group G, an explicit Kähler-Einstein metric on it is constructed. The Einstein constant for the metric is 1. Therefore, the intersection number of the first Chern class of the holomorphic tangent bundle of G/P coin
Let (X, O X ) be a compact (reduced) complex space, bimeromorphic to a Kähler manifold. The singular cohomology groups H q (X, C) carry a mixed Hodge structure. In particular they carry a weight filtration W -l H q (X, C) (l = 0, . . . , q), and the graded quotients C) have a direct sum decompositio
