We consider two different vacuum decay scenarios: the Coleman-de Luccia $\\mathrm{O}(4)$-symmetric bubble, and $\\mathrm{O}(3) \\times \\mathbb{R}$ instantons with a static black hole. In spite of the similarities between the models, we find qualitatively different behaviours. In the $\\mathrm{O}(4)$-symmetric case, the number of negative modes is known to be either one or infinite, depending on the sign of the kinetic term in the quadratic action. In contrast, solving the mode equat","authors_text":"Florent Michel, Ian G. Moss, Katie M.
