“…Examples of situations where this behaviour may be the case are found in the context of BIon solutions [43,44] and M2-M5 intersections [45][46][47]. If the geometry has boundaries, this could potentially signify that the geometry near the boundary would have to be replaced by something else than (2.10) but which would smoothly connect to (2.10).…”

Minimal surfaces in Euclidean space provide examples of possible non-compact horizon geometries and topologies in asymptotically flat space-time. On the other hand, the existence of limiting surfaces in the space-time provides a simple mechanism for making these configurations compact. Limiting surfaces appear naturally in a given space-time by making minimal surfaces rotate but they are also inherent to plane wave or de Sitter spacetimes in which case minimal surfaces can be static and compact. We use the blackfold approach in order to scan for possible black hole horizon geometries and topologies in asymptotically flat, plane wave and de Sitter space-times. In the process we uncover several new configurations, such as black helicoids and catenoids, some of which have an asymptotically flat counterpart. In particular, we find that the ultraspinning regime of singly-spinning Myers-Perry black holes, described in terms of the simplest minimal surface (the plane), can be obtained as a limit of a black helicoid, suggesting that these two families of black holes are connected. We also show that minimal surfaces embedded in spheres rather than Euclidean space can be used to construct static compact horizons in asymptotically de Sitter space-times.

“…Another motivation for this work is the recent proposal [30] (see also [31] for related independent work building on [17,32,33]) that the effective hydrodynamic description of black brane solutions in the blackfold formalism is connected to the underlying microscopic description of D/M-branes in string/M-theory via a general open/closed string duality that works in many cases in gravity as a tomographic principle. In the proposal of ref.…”

We present a general treatment of the leading order dynamics of the collective modes of charged dilatonic p-brane solutions of (super)gravity theories in arbitrary backgrounds. To this end we employ the general strategy of the blackfold approach which is based on a long-wavelength derivative expansion around an exact or approximate solution of the (super)gravity equations of motion. The resulting collective mode equations are formulated as forced hydrodynamic equations on dynamically embedded hypersurfaces. We derive them in full generality (including all possible asymptotic fluxes and dilaton profiles) in a far-zone analysis of the (super)gravity equations and in representative examples in a near-zone analysis. An independent treatment based on the study of external couplings in hydrostatic partition functions is also presented. Special emphasis is given to the forced collective mode equations that arise in type IIA/B and eleven-dimensional supergravities, where besides the standard Lorentz force couplings our analysis reveals additional couplings to the background, including terms that arise from Chern-Simons interactions. We also present a general overview of the blackfold approach and some of the key conceptual issues that arise when applied to arbitrary backgrounds.

“…It may be noted there the F1-D3 intersection is U-dual to a system of M2-M5 branes [26]- [27]. The M2-branes intersecting with M5-branes have been analyzed in the supergravity regime [28]- [29].…”

“…In this paper, we will also use the formalism of holographic cosmology [38]- [41], to discuss the state of the universe before such a collision occurs. It may be noted that such a model has also been studied using BIonic solution [22]- [25], and such a system is U-dual to a system of M2-M5 branes [26]- [27]. So, this system is actually U-dual to the BIonic cosmology.…”

Holographic cosmology from a system of M2–M5 branes

In this paper, we analyze the holographic cosmology using a M2-M5 brane configuration. In this configuration, a M2-brane will be placed in between a M5-brane and an anti-M5-brane. The M2-brane will act as a channel for energy to flow from an anti-M5-brane to a M5-brane, and this will increase the degrees of freedom on the M5-brane causing inflation. The inflation will end when the M5-brane and anti-M5-brane get separated. However, at a later stage the distance between the M5-brane and the anti-M5-bran can reduce and this will cause the formation of tachyonic states. These tachyonic states will be again open a bridge between the M5-branes and the anti-M5-branes, which will cause further acceleration of the universe.
