Novel accelerating Einstein vacua and smooth inhomogeneous Riemannian
manifolds    [PDF]

Kun Meng, Wei Xu, Liu Zhao

A novel class of Einstein vacua is presented, which possess non-vanishing cosmological constant and accelerating horizon with the topology of $S^{D-3}$ fibration over $S^{1}$. After Euclideanization, the solution describes a conformally distorted $S^{D-1}$ fibration over $S^1$, which is smooth, compact and inhomogeneous, and can be regarded as analogue of Don Page's gravitational instanton.
