Gravitational Stability and Renormalization-Group Flow
Kostas Skenderis, Paul K. Townsend
First-order `Bogomol'nyi' equations are found for dilaton domain walls of D-dimensional gravity with the general dilaton potential admitting a stable anti-de Sitter vacuum. Implica…
Supersymmetric Baryonic Branes
Joaquim Gomis, Alfonso Ramallo, Joan Simon +1
We derive an energy bound for a `baryonic' D5-brane probe in the background near the horizon of D3-branes. Configurations saturating the bound are shown to be…
Supersymmetry and generalized calibrations
J. Gutowski, G. Papadopoulos, P. K. Townsend
A static minimal energy configuration of a super p-brane in a supersymmetric (n+1)-dimensional spacetime is shown to be a `generalized calibrated' submanifold. Calibrations in $\bE…
Finite energy Dirac-Born-Infeld monopoles and string junctions
Jerome Gauntlett, Chris Koehl, David Mateos +2
It is shown that the worldvolume field theory of a single D3-brane in a supergravity D3-brane background admits finite energy, and non-singular, abelian monopoles and dyons preserv…
The M(atrix) model/adS_2 correspondence
P. K. Townsend
The M(atrix) model has a dual realization as IIA superstring theory in the near-horizon geometry of the supergravity D0-brane. The role of in this correspondence is reviewe…
Killing spinors, supersymmetries and rotating intersecting branes
P. K. Townsend
I review a recently proposed method for determining the symmetry superalgebra of a supergravity configuration from its Killing spinors, and its application to the `near-horizon' li…
