Stability of asymptotically flat (2+1)-dimensional black holes with Gauss-Bonnet corrections

Abstract

Using the integration of wave equation in time-domain we show that scalar field perturbations around the $(2+1)$-dimensional asymptotically flat black hole with Gauss-Bonnet corrections is dynamically stable even for the near extreme values of the coupling constant.

The title is changed. Corrections inserted. (4 pages, 2 figures)
