# Stiff fluid spike solutions from Bianchi type V seed solutions

## TL;DR

This paper generates new exact solutions in cosmology using Bianchi type V seed solutions and Stephani transformation, revealing phenomena like intersecting spikes, saddle states, and near-Friedmann-Lemaître epochs.

## Contribution

It extends previous work by applying the Stephani transformation to the full Bianchi type V family, uncovering novel physical phenomena in the solutions.

## Key findings

- Discovery of solutions with intersecting spikes
- Identification of saddle state solutions
- Solutions with a close-to-FL epoch

## Abstract

In this paper we expand upon our previous work [1] by using the entire family of Bianchi type V stiff fluid solutions as seed solutions of the Stephani transformation. Among the new exact solutions generated, we observe a number of important physical phenomena. The most interesting phenomenon is exact solutions with intersecting spikes. Other interesting phenomena are solutions with saddle states and a close-to-FL epoch.
