متن کاملNumerical 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...
متن کاملNumerical 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...
متن کاملAsymptotic silence of generic cosmological singularities.
In this Letter we investigate the nature of generic cosmological singularities using the framework developed by Uggla et al. We study the past asymptotic dynamics of general vacuum G2 cosmologies, which are expected to capture the singular behavior of generic cosmologies with no symmetries at all. Our results indicate that asymptotic silence holds, i.e., particle horizons along all time lines s...
متن کاملOn Phases of Generic Toric Singularities
We systematically study the phases of generic toric singularities, using methods initiated in hep-th/0612046. These correspond to Gauged Linear Sigma Models with arbitrary charges. We show that complete information about generic U(1) GLSMs can be obtained by studying the GLSM Lagrangian, appropriately modified in the different phases of the theory. This can be used to study the different phases...
