Absorption coefficient five dimensions scalar field a black hole the parameter space
2014/12/22
An expression for the spacetime absorption coefficient of a scalar field in a five-dimensional, near-extremal black hole background is derived, which has the same form as that presented by Maldacena a...
Overlapping branes in M-theory
Membrane separation overlapping cross membrane membrane cross membrane
2014/12/22
We construct new supersymmetric solutions of D = 11 supergravity describing n orthogonally “overlapping” membranes and fivebranes for n = 2,…,8. Overlapping branes arise after separating intersecting ...
From wrapped M-branes to Calabi-Yau black holes and strings
Time and space time and space movement equation the black hole black string
2014/12/20
We study a class of D = 11 BPS spacetimes that describe M-branes wrapping supersymmetric 2 and 4-cycles of Calabi-Yau 3-folds. We analyze the geometrical significance of the supersymmetry constraints ...

Black string membrane pure Einstein gravitational black holes vacuum constant curvature space
2014/12/20
It is well known that black strings and branes may be constructed in pure Einstein gravity simply by adding flat directions to a vacuum black hole solution. A similar construction holds in the presenc...

Abstract: Exact solvability of brane equations is studied, and a new $U(1)xU(1)x...xU(1)$ invariant anzats for the solution of p-brane equations in D=(2p+1)-dimensional Minkowski space is proposed. Th...
D-branes of A-type, their deformations, and Morse cobordism of A-branes on Calabi-Yau 3-folds under a split attractor flow: Donaldson/Alexander-Hilden-Lozano-Montesinos-Thurston/Hurwitz/Denef-Joyce meeting Polchinski-Grothendieck

2011/1/17
In [L-Y5] (D(6): arXiv:1003.1178 [math.SG]) we introduced the notion of Azumaya C1-manifolds with a fundamental module and morphisms therefrom to a complex manifold. In the current sequel, we use this...

2011/3/2
A supersymmetric quantum mechanical model is constructed for BPS states bound to surface operators in five dimensional SU(r) gauge the-ories using D-brane engineering.
We obtain a family of supersymmetric solutions of type IIB supergravity with dynamic SU(2) structure, which describe the local geometry near a stack of four D7-branes and one O7-plane wrapping a rigi...

We describe a concise general scheme for constructing solutions of Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting self-consistently with one or more (widely separate...
The Spectrum of FZZT Branes Beyond the Planar Limit
The Spectrum of FZZT Branes Planar Limit
2010/12/24
Minimal string theory has a number of FZZT brane boundary states; one for each Cardy state of the minimal model. It was conjectured by Seiberg and Shih that all branes in a minimal string theory coul...

2010/12/24
In a recent paper published in this journal, Bazeia and collaborators [Phys. Lett. B 671, (2009) 402] analyze braneworld models with nonstandard dynamics. It was found that the generalized braneworld...

The supersymmetric actions of closed multiple M2 branes with flux for the BL and the ABJM theories have been constructed recently by Lambert and Richmond in \cite{LR}. In this paper we extend the con...

We find the superpotential governing the supersymmetric warped M-theory solution with a transverse Stenzel space found by Cvetic, Gibbons, Lu and Pope in hep-th/0012011, and use this superpotential to...
