### The nature of cosmological singularities in isotropic universes and braneworlds

- Mathematics
- 2008

We explore the character of finite-time singularities that are possible to arise in FRW universes and in specific braneworld configurations. For FRW universes, we derive a first classification of…

Vacuum expectation value of the surface energy-momentum tensor is evaluated for a massive scalar field with general curvature coupling parameter subject to Robin boundary conditions on two parallel…

### Review of Bounds on the Graviton Mass, from the Influence of Early Universe Magnetic Fields Right at Start of Inflation

- Physics
- 2015

We use the results of A. Montiel et al, as to the contribution of energy density of non linear magnetic components to RW inflationary physics, as well as the standard of ephemeris time to come up…

### How a Randall‐Sundrum Brane‐World Effective Potential Influences Inflation Physics

- Physics
- 2007

In string theory, even when there are ten to the thousand power vacuum states, does inflation produce overwhelmingly one preferred type of vacuum state? We respond affirmatively to questions whether…

### Analyzing If a Graviton Gas Acts Like a Cosmological Vacuum State and “Cosmological” Constant Parameter

- Physics
- 2010

If a non-zero graviton mass exists, the question arises if a release of gravitons, possibly as a “Graviton gas” at the onset of inflation could be an initial vacuum state. Pros and cons to this idea…

### How can Brane World physics influence Axion temperature dependence, initial vacuum states, and permissible solutions to the Wheeler-De Witt equation?

- Physics
- 2006

We are investigating if the Jeans instability criteria mandading a low entropy,low temperature initial pre inflation state configuration can be recociled with thermal conditions of temperature at or…

### Symmetries in evolving space time from present to prior universes

- Mathematics
- 2005

We wish to demonstrate how the presence of a dynamic cosmological parameter, plus a model of the universe as a quantum computer can be combined to give us a picture of early universe inflationary…

### Randall-Sundrum model for self-tuning the cosmological constant.

- PhysicsPhysical review letters
- 2001

The vanishing cosmological constant in the four-dimensional space-time is obtained in a 5D Randall-Sundrum model with a brane (B1) located at y = 0 and a three-index antisymmetric tensor field A(MNP) with a specific form for the Lagrangian.

### Gravity in the randall-sundrum brane world

- PhysicsPhysical review letters
- 2000

The weak gravitational field created by isolated matter sources in the Randall-Sundrum brane world is discussed and the leading Kaluza-Klein corrections to the linearized gravitational field of a nonrelativistic spherical object is calculated.

### Exact description of black holes on branes

- Physics
- 2000

To test recent ideas about lower dimensional gravity bound to a brane, we construct exact solutions describing black holes on two-branes in four dimensions. We find that 2+1 gravity is indeed…

### Brane world black holes

- Physics
- 2000

Gravitational collapse of matter trapped on a brane will produce a black hole on the brane. We discuss such black holes in the models of Randall and Sundrum where our universe is viewed as a domain…

It was recently pointed out that global solutions of Einstein's equations for a 3-brane universe embedded in four spatial dimensions give rise to a Friedmann equation of the form…

We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises…
