TL;DR: In this paper, a cosmological constant Λ was used to classify the cold black holes and, for positive Λ, the "lukewarm" black holes at the same temperature as the de Sitter thermal background.

TL;DR: In this article, the authors constructed a supergravity N = 8 theory in five dimensions with fifteen vector fields and twelve second-rank antisymmetric tensor fields satisfying self-dual field equations.

TL;DR: In this article, a detailed construction of N = 8 supergravity theories in five dimensions with Yang-Mills gauge groups SO(p, 6−p), physical global symmetry SU(1, 1), and local composite symmetry USp(8).

TL;DR: In this article, a list of all homogeneous 7-manifolds which admit an Einstein metric is given, with some emphasis on the SU(3) × SU(2) × U(1) compactifications.

TL;DR: In this article, a number of new compactifying solutions of chiral N = 2 ten-dimensional supergravity to five dimensions were presented, all of which are of the standard Freund-Rubin type; they give a complete classification of compactifications for which the internal space M 5 is a coset manifold.
