A G_2 Unification of the Deformed and Resolved Conifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
We find general first-order equations for G_2 metrics of cohomogeneity one with S^3\times S^3 principal orbits. These reduce in two special cases to previously-known systems of fir…
M-theory Conifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
Seven-manifolds of G_2 holonomy provide a bridge between M-theory and string theory, via Kaluza-Klein reduction to Calabi-Yau six-manifolds. We find first-order equations for a new…
Orientifolds and Slumps in G_2 and Spin(7) Metrics
M. Cvetic, G. W. Gibbons, H. Lu +1
We discuss some new metrics of special holonomy, and their roles in string theory and M-theory. First we consider Spin(7) metrics denoted by C_8, which are complete on a complex li…
Supersymmetric Domain Walls from Metrics of Special Holonomy
G. W. Gibbons, H. Lu, C. N. Pope +1
Supersymmetric domain-wall spacetimes that lift to Ricci-flat solutions of M-theory admit generalized Heisenberg (2-step nilpotent) isometry groups. These metrics may be obtained f…
Cohomogeneity One Manifolds of Spin(7) and G(2) Holonomy
M. Cvetic, G. W. Gibbons, H. Lu +1
In this paper, we look for metrics of cohomogeneity one in D=8 and D=7 dimensions with Spin(7) and G_2 holonomy respectively. In D=8, we first consider the case of principal orbits…
Resolved Branes and M-theory on Special Holonomy Spaces
Mirjam Cvetic, G. W. Gibbons, H. Lu +1
We review the construction of regular p-brane solutions of M-theory and string theory with less than maximal supersymmetry whose transverse spaces have metrics with special holonom…
A New Fractional D2-brane, G_2 Holonomy and T-duality
M. Cvetic, G. W. Gibbons, James T. Liu +2
Recently, a new example of a complete non-compact Ricci-flat metric of G_2 holonomy was constructed, which has an asymptotically locally conical structure at infinity with a circul…
Supersymmetric M3-branes and G_2 Manifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
We obtain a generalisation of the original complete Ricci-flat metric of G_2 holonomy on R^4\times S^3 to a family with a non-trivial parameter λ. For generic λthe solution is sing…
New Cohomogeneity One Metrics With Spin(7) Holonomy
M. Cvetic, G. W. Gibbons, H. Lu +1
We construct new explicit non-singular metrics that are complete on non-compact Riemannian 8-manifolds with holonomy Spin(7). One such metric, which we denote by A_8, is complete a…
New Complete Non-compact Spin(7) Manifolds
M. Cvetic, G. W. Gibbons, H. Lu +1
We construct new explicit metrics on complete non-compact Riemannian 8-manifolds with holonomy Spin(7). One manifold, which we denote by A_8, is topologically R^8 and another, whic…
Pulse Propagation in Born-Infeld Theory, the World Volume Equivalence Principle and the Hagedorn-like Equation of State of the Chaplygin Gas
G W Gibbons
A recently proposed world-volume equivalence principal involving the Boillat, as opposed to the Einstein, metric is examined in the context of some colliding wave solutions of the…
Hyper-Kahler Calabi Metrics, L^2 Harmonic Forms, Resolved M2-branes, and AdS_4/CFT_3 Correspondence
M. Cvetic, G. W. Gibbons, H. Lu +1
We obtain a simple explicit expression for the hyper-Kahler Calabi metric on the co-tangent bundle of CP^{n+1}, for all n, in which it is constructed as a metric of cohomogeneity o…
Supersymmetric Non-singular Fractional D2-branes and NS-NS 2-branes
M. Cvetic, G. W. Gibbons, H. Lu +1
We obtain regular deformed D2-brane solutions with fractional D2-branes arising as wrapped D4-branes. The space transverse to the D2-brane is a complete Ricci-flat 7-manifold of G_…
