Scalar Cosmology with Multi-exponential Potentials
Andres Collinucci, Mikkel Nielsen, Thomas Van Riet
We investigate cosmologies with an arbitrary number of scalars and the most general multi-exponential potential. By formulating the equations of motion in terms of autonomous syste…
The Domain Walls of Gauged Maximal Supergravities and their M-theory Origin
Eric Bergshoeff, Mikkel Nielsen, Diederik Roest
We consider gauged maximal supergravities with CSO(p,q,r) gauge groups and their relation to the branes of string and M-theory. The gauge groups are characterised by n mass paramet…
Transient Quintessence from Group Manifold Reductions or how all roads lead to Rome
Eric Bergshoeff, Andres Collinucci, Ulf Gran +2
We investigate the accelerating phases of cosmologies supported by a metric, scalars and a single exponential scalar potential. The different solutions can be represented by trajec…
The Bianchi Classification of Maximal D=8 Gauged Supergravities
Eric Bergshoeff, Ulf Gran, Roman Linares +3
We perform the generalised dimensional reduction of D=11 supergravity over three-dimensional group manifolds as classified by Bianchi. Thus, we construct eleven different maximal D…
Domain Walls and the Creation of Strings
Eric Bergshoeff, Ulf Gran, Roman Linares +2
The phenomenon of creation of strings, occurring when particles pass through a domain wall and related to the Hanany-Witten effect via dualities, is discussed in ten and nine dimen…
Deformation independent open brane metrics and generalized theta parameters
David S. Berman, Martin Cederwall, Ulf Gran +4
We investigate the consequences of generalizing certain well established properties of the open string metric to the conjectured open membrane and open Dp-brane metrics. By imposin…
