Abstract We study homogeneous Einstein metrics on indecomposable non-Kahler C-spaces, i.e. even-dimensional torus bundles M = G ∕ H with rank > over flag manifolds F K of a compact simple Lie group . Based the theory painted Dynkin diagrams we present classification such spaces. Next focus family l , m n ≔ SU ( + ) × ∈ Z and examine several its geometric properties. show that invariant are not ...

The consistency of the constraint with the evolution equations for spatially inhomogeneous and irrotational silent (SIIS) models of Petrov type I, demands that the former are preserved along the timelike congruence represented by the velocity of the dust fluid, leading to new non-trivial constraints. This fact has been used to conjecture that the resulting models correspond to the spatially hom...
