# A note about the perturbative dynamics of symmetric shells

## TL;DR

This paper discusses how the choice of equations of state influences the monotonic evolution of perturbed symmetric thin-shells, highlighting the importance of modeling assumptions in their dynamical behavior.

## Contribution

It emphasizes the role of the equations of state approximation in the perturbative dynamics of symmetric shells, providing insights into their evolution.

## Key findings

- Equations of state significantly affect shell dynamics.
- Symmetric shells exhibit monotonic evolution under certain conditions.
- Modeling assumptions are crucial for accurate dynamical predictions.

## Abstract

Several examples suggest the conjecture that the central aspect determining a monotonic evolution for perturbed highly symmetric thin-shells is the approximation adopted for their equations of state.
