SO(5,5) duality in M-theory and generalized geometry
David S. Berman, Hadi Godazgar, Malcolm J. Perry
We attempt to reformulate eleven dimensional supergravity in terms of an object that unifies the three-form and the metric and makes the M-theory duality group manifest. This short…
Kac-Moody and Virasoro Symmetries of Principal Chiral Sigma Models
H. Lu, M. J. Perry, C. N. Pope +1
It is commonly asserted that there is a \hat G\times G centreless Kac-Moody extension of the manifest G\times G global symmetry of the two-dimensional principal chiral model (PCM)…
Infinite-Dimensional Symmetries of Two-Dimensional Coset Models
H. Lu, M. J. Perry, C. N. Pope
It has long been appreciated that the toroidal reduction of any gravity or supergravity to two dimensions gives rise to a scalar coset theory exhibiting an infinite-dimensional glo…
Partition Functions, the Bekenstein Bound and Temperature Inversion in Anti-de Sitter Space and its Conformal Boundary
G. W. Gibbons, M. J. Perry, C. N. Pope
We reformulate the Bekenstein bound as the requirement of positivity of the Helmholtz free energy at the minimum value of the function L=E- S/(2πR), where R is some measure of the…
The First Law of Thermodynamics for Kerr-Anti-de Sitter Black Holes
G. W. Gibbons, M. J. Perry, C. N. Pope
We obtain expressions for the mass and angular momenta of rotating black holes in anti-de Sitter backgrounds in four, five and higher dimensions. We verify explicitly that our expr…
Off-shell structure of the string sigma model
Alan Kostelecky, Malcolm Perry, Robertus Potting
The off-shell structure of the string sigma model is investigated. In the open bosonic string, nonperturbative effects are shown to depend crucially on the regularization scheme. A…
Non-BPS D8-branes and Dynamic Domain Walls in Massive IIA Supergravities
A. Chamblin, M. J. Perry, H. S. Reall
We study the D8-branes of the Romans massive IIA supergravity theory using the coupled supergravity and worldvolume actions. D8 branes can be regarded as domain walls with the jump…
Ricci-Flat Branes
D. Brecher, M. J. Perry
Up to overall harmonic factors, the D8-brane solution of the massive type IIA supergravity theory is the product of nine-dimensional Minkowski space (the worldvolume) with the real…
Compactification of Supermembranes
C. Codirla, M. J. Perry
We look at the vertical dimensional reduction of the supermembrane of M-theory to the D2-brane of Type IIA string theory. Our approach considers the soliton solutions of the two lo…
The No-ghost Theorem for AdS_3 and the Stringy Exclusion Principle
J. M. Evans, M. R. Gaberdiel, M. J. Perry
A complete proof of the No-ghost Theorem for bosonic and fermionic string theories on AdS_3, or the group manifold of SU(1,1), is given. It is then shown that the restriction on th…
Bound States of D-Branes and the Non-Abelian Born-Infeld Action
D. Brecher, M. J. Perry
We attempt to settle the issue as to what is the correct non-abelian generalisation of the Born-Infeld action, via a consideration of the two-loop --function for the non-abelian…
String-Dominated Cosmology
Dalia S. Goldwirth, Malcolm J. Perry
If string theory controls physics at the string scale, the dynamics of the early universe before the GUT era will be governed by the low-energy string equations of motion. Studying…
Kleinian Geometry and the N=2 Superstring
J. Barrett, G. W. Gibbons, M. J. Perry +2
This paper is devoted to the exploration of some of the geometrical issues raised by the superstring. We begin by reviewing the reasons that -functions for the super…
Non-Singularity of the Exact Two-Dimensional String Black Hole
Malcolm J. Perry, Edward Teo
We study the global structure of the exact two-dimensional space-time which emerges from string theory. Previous work has shown that in the semi-classical limit, this is a black ho…
