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

Using the integration of wave equation in the time-domain we show that scalar field perturbations around the (2 + 1)-dimensional asymptotically flat black hole with Gauss-Bonnet corrections are dynamically stable even for the near extreme values of the coupling constant. © 2023 – SU in Opava.
