Nonsingular bouncing cosmology from general relativity: Scalar metric perturbations
F. R. Klinkhamer, Z. L. Wang
We derive the equations of motion for scalar metric perturbations in a particular nonsingular bouncing cosmology, where the big bang singularity is replaced by a spacetime defect w…

Asymmetric nonsingular bounce from a dynamic scalar field
F. R. Klinkhamer, Z. L. Wang
We present a dynamical model for a time-asymmetric nonsingular bounce with a post-bounce change of the effective equation-of-state parameter. Specifically, we consider a scalar-fie…

Nonsingular bouncing cosmology from general relativity
F. R. Klinkhamer, Z. L. Wang
We investigate a particular type of classical nonsingular bouncing cosmology, which results from general relativity if we allow for degenerate metrics. The simplest model has a mat…
