The Superconformal Gaugings in Three Dimensions
Eric A. Bergshoeff, Olaf Hohm, Diederik Roest +2
We show how three-dimensional superconformal theories for any number N <= 8 of supersymmetries can be obtained by taking a conformal limit of the corresponding three-dimensional ga…
Ricci-Flat and Charged Wormholes in Five Dimensions
H. Lu, Jianwei Mei
We construct stationary Ricci-flat inter-universe Lorentzian wormhole solutions in all D\ge 5 dimensions that connect two flat asymptotic spacetimes. Such a solution can be viewed…
New Black Holes in Five Dimensions
H. Lu, Jianwei Mei, C. N. Pope
We construct new stationary Ricci-flat metrics of cohomogeneity 2 in five dimensions, which generalise the Myers-Perry rotating black hole metrics by adding a further non-trivial p…
Metrics With Vanishing Quantum Corrections
A. A. Coley, G. W. Gibbons, S. Hervik +1
We investigate solutions of the classical Einstein or supergravity equations that solve any set of quantum corrected Einstein equations in which the Einstein tensor plus a multiple…
Simple Bounds from the Perturbative Regime of Inflation
Louis Leblond, Sarah Shandera
We examine the conditions under which a perturbative expansion around an inflating background is valid. When inflation is driven by a single field with a general sound speed, we fi…
Infinite-Dimensional Symmetries of Two-Dimensional Coset Models Coupled to Gravity
M. J. Perry, H. Lu, C. N. Pope
In an earlier paper we studied the infinite-dimensional symmetries of symmetric-space sigma models (SSMs) in a flat two-dimensional spacetime. Here, we extend our investigation to…
