U duality, D-branes, and black hole emission rates: Agreements and disagreements
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...
From wrapped M-branes to Calabi-Yau black holes and strings
Time and space time and space movement equation the black hole black string

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...

We study fundamental string (F-string) dynamics near D5-brane in some limits. We find that when the angular momentum of the probe is proportional to string length (l_s) and square root of string coupl...
An old Einstein - Eddington generalized gravity and modern ideas on branes and cosmology

2010/12/20
We briefly discuss new models of an ‘affine’ theory of gravity in multidimensional space-times with symmetric connections. We use and generalize Einstein’s proposal to specify the space-time geometry ...
