“…In particular, we examine some intersecting S-brane solutions. According to the intersection rules [5,22], we can construct an SM2-SM5 intersecting solution that leads to a 4-dimensional universe as follows:…”

We present a systematic study of accelerating cosmologies obtained from M/string theory compactifications of hyperbolic spaces with time-varying volume. A set of vacuum solutions where the internal space is a product of hyperbolic manifolds is found to give qualitatively the same accelerating four-dimensional FLRW universe behavior as a single hyperbolic space. We also examine the possibility that our universe is a hyperbolic space and provide exact Milne type solutions, as well as intersecting S-brane solutions. When both the usual 4D spacetime and the m-dimensional internal space are hyperbolic, we find eternally accelerating cosmologies for m ≥ 7, with and without form field backgrounds. In particular, the effective potential for a magnetic field background in the large 3 dimensions is positive definite with a local minimum and thus enhances the eternally accelerating expansion.

“…For magnetic (electric) field background, the field strength should be of the form 22) where is the volume form of either H 3 or H m . Due to electric magnetic duality, we only have to consider, say, the electric and magnetic background (5.22) with being the volume form on H 3 .…”

“…These solutions deal with time-dependent scale factors of internal spaces (for reviews see [5,6,8,9]) and contain as a special case the so-called S-brane solutions [10], i.e. space like analogues of D -branes [18], see for example [11,12,13,14,15,16,17] and references therein. For earlier S -brane solutions see also [19,20,21].…”

A family of generalized S -brane solutions with orthogonal intersection rules and n Ricci-flat factor spaces in the theory with several scalar fields and antisymmetric forms is considered. Two subclasses of solutions with power-law and exponential behaviour of scale factors are singled out. These subclasses contain sub-families of solutions with accelerated expansion of certain factor spaces. The solutions depend on charge densities of branes, their dimensions and intersections, dilatonic couplings and the number of dilatonic fields.

“…Other developements in this direction include [14,15,16]. This holographic description has been invoked in a number of works to study different aspects of Randall-Sundrum models [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

It has been proposed that Randall-Sundrum models can be holographically described by a regularized (broken) conformal field theory. We analyze the foundations of this duality using a regularized version of the AdS/CFT correspondence. We compare twoand three-point correlation functions and find the same behaviour in both descriptions. In particular, we show that the regularization of the deformed CFT generates kinetic terms for the sources, which hence can be naturally treated as dynamical fields. We also discuss the counterterms required for two-and three-point correlators in the renormalized AdS/CFT correspondence.
