Asymptotic Stability Analysis for Dark Monopoles
M.L. Deglmann🇧🇷 · Marco A.C. Kneipp🇧🇷
Abstract
We analyze the asymptotic stability of the Dark Monopole solutions and we show that there are unstable modes associated with them. We obtain the explicit form of the unstable perturbations and the associated negative-squared eigenfrequencies.
