| Description |
A boundary-value method for finding quasinormal frequencies is presented here for the first time. Results are derived for the application of the one-dimensional form of the method to two quasinormal mode systems where the correct quasinormal frequencies can be determined analytically. Calculations show that when a sufficiently precise approximation (asymptotic expansion) is made to the radiative boundary conditions, then accurate results can be obtained for the least damped quasinormal frequencies. The paper is concluded with a qualitative explanation of the relationship that exists between the accuracy of the method, the point at which an approximate radiative boundary condition is implemented, and the number of terms kept in the asymptotic expansion. |
