| Research Abstract |
An elastic wave equation in a homogeneous, isotropic, elastic half-space with a free boundary and with a constant density and constant body-wave velocities has been investigated as a simple model of the equation describing the seismic wave propagation. We study a relation between asymptotic behavior of a generalized eigenfunction to the stationary elastic wave equation and the Fourier transform associated with the elastic wave equation. In this research, we obtained that the set of solutions can be described by the Fourier transform and the asymptotic expansion of the solution can be evaluated for all direction.
