Numerical confirmations of joint spike transitions in $G_2$ cosmologies
Woei Chet Lim
TL;DR
This paper provides numerical evidence that joint spike transitions in $G_2$ cosmologies are accurately described by a specific spike solution, supported by a new matching procedure.
Contribution
It introduces a new matching procedure and confirms the spike solution's role in joint transitions in $G_2$ cosmologies.
Findings
Numerical evidence supports the spike solution description.
A new matching procedure is developed.
Joint spike transitions are characterized by the non-orthogonally transitive $G_2$ spike solution.
Abstract
We produce numerical evidence that the joint spike transitions between Kasner eras of cosmologies are described by the non-orthogonally transitive spike solution. A new matching procedure is developed for this purpose.
