Numerical investigation of cosmological singularities.

A primary unresolved issue for cosmological singularities is whether or not their behavior is locally of the Mixmaster type (as conjectured by Belinskii, Khalatnikov, and Lifshitz (BKL)). The Mixmaster dynamics first appears in spatially homogeneous cosmologies of Bianchi Types VIII and IX. A multiple of the spatial scalar curvature acts as a closed potential leading, in the evolution toward th...

Numerical Investigation of Singularities

Numerical exploration of the properties of singularities could, in principle, yield detailed understanding of their nature in physically realistic cases. Examples of numerical investigations into the formation of naked singularities, critical behavior in collapse, passage through the Cauchy horizon, chaos of the Mixmaster singularity, and singularities in spatially inhomogeneous cosmololgies ar...

Cosmological Singularities *

An overview is provided of the singularity theorems in cosmological contexts at a level suitable for advanced graduate students. The necessary background from tensor and causal geometry to understand the theorems is supplied, the mathematical notion of a cosmology is described in some detail and issues related to the range of validity of general relativity are also discussed. ∗To be published i...

Resolution of Cosmological Singularities

We show that a class of 3+1 dimensional Friedmann-RobertsonWalker cosmologies can be embedded within a variety of solutions of string theory. In some realizations the apparent singularities associated with the big bang or big crunch are resolved at non-singular horizons of higher-dimensional quasi-black hole solutions (with compactified real time); in others plausibly they are resolved at D-bra...

Cosmological theory without singularities.

A theory of gravitation is constructed in which all homogeneous and isotropic solutions are nonsingular, and in which all curvature invariants are bounded. All solutions for which curvature invariants approach their limiting values approach de Sitter space. The action for this theory is obtained by a higher-derivative modification of Einstein s theory. We expect that our model can easily be gen...
