Cosmology as Geodesic Motion
Paul K. Townsend, Mattias N. R. Wohlfarth
For gravity coupled to N scalar fields with arbitrary potential V, it is shown that all flat (homogeneous and isotropic) cosmologies correspond to geodesics in an (N+1)-dimensional…
Fuzzy CP(n|m) as a quantum superspace
Evgeny Ivanov, Luca Mezincescu, Paul K. Townsend
The `Chern-Simons Quantum Mechanics' of a particle on CP(n|m) is shown to yield the fuzzy descriptions of these superspaces, for which we construct the non-(anti)commuting position…
Cosmic Acceleration and M-Theory
Paul K. Townsend
The status of accelerating four-dimensional universes obtained by time-dependent compactifications of 10 or 11 dimensional supergravity is reviewed, as is the `no-go' theorem that…
The Story of M
Paul K. Townsend
The origins of the 11-dimensional supermembrane are recalled, and a curious property is discussed: the field theory limit of a supermembrane in a hyper-Kähler background is a 3-dim…
Brane Theory Solitons
P. K. Townsend
Field theories that describe {\sl small} fluctuations of branes are limits of `brane theories' that describe {\sl large} fluctuations. In particular, supersymmetric sigma-models ar…
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…
