We describe new no-go theorems for producing four-dimensional accelerating universes from warped dimensional reduction. The new theorems improve upon previous results by including dynamical extra dimensions and by treating four-dimensional universes that are not precisely de Sitter. The theorems show there exists a threshold four-dimensional equation-of-state parameter w below which the number of e-foldings of expansion is bounded, and give expressions for the maximum number of allowed e…

A no-go for no-go theorems prohibiting cosmic acceleration in extra dimensional models

A four-dimensional effective theory that arises as the low-energy limit of some extra-dimensional model is constrained by the higher dimensional Einstein equations. Steinhardt & Wesley use this to

Multidimensional Treatment of the Expanding Universe

The simplest six-dimensional treatment of the expanding Universe in the form a three- dimensional sphere appeared as a result of the intersection of three simplest geometrical objects of finite sizes

We give detailed proofs of several new no-go theorems for constructing flat fourdimensional accelerating universes from warped dimensional reduction. These new theorems improve upon previous ones by

Codimension-2 brane–bulk matching: examples from six and ten dimensions

Experience with Randall–Sundrum models teaches the importance of following how branes back-react onto the bulk geometry, since this can dramatically affect the system's low-energy properties. Yet the

EFT for vortices with dilaton-dependent localized flux

A bstractWe study how codimension-two objects like vortices back-react gravitationally with their environment in theories (such as 4D or higher-dimensional supergravity) where the bulk is described

Nonsupersymmetric Flux Vacua and Perturbed N=2 Systems

We geometrically engineer Script N = 2 theories perturbed by a superpotential by adding 3-form flux with support at infinity to local Calabi-Yau geometries in type IIB. This allows us to apply the

Tunneling with negative tension

We describe a new family of thin-wall instantons, with negative tension bubble walls, that mediate tunneling between Minkowski or de Sitter vacua. Some of these instantons can have exponentially

These lectures give a detailed introduction to constructing and analyzing string vacua suitable for phenomenological model building, with particular emphasis on F-theory flux vacua. Topics include

The Large Scale Structure of Space-Time

The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.

    This may not be a significant exclusion, since the DGP model suffers from ghosts in the branch most relevant for cosmic acceleration
