Abstract
This work studies the stability of fluctuating Baby-Skyrme brane as a model for early-time cosmology. The dynamical system consists of two dynamical quantities \((\phi,H)\) with two differential equations and one constraint. The solutions can be realized as a family of curves on a surface in \(\mathbb{R}^3\). We found that there exist stable solutions provided that the physical parameters \((\alpha,\sigma,k)\) satisfy certain conditions that are deduced from the linear stability conditions near the critical points.
