报告摘要: We consider the determination of anisotropic perturbation of an isotropic elastic body from travel-time measurement. For the perturbation of P waves, we arrived at a standard tensor tomography of a rank-four tensor on a Riemannian manifold. Perturbation of S waves gives a mixed ray transform of a different (but closely related) rank-four tensor. We discuss the uniqueness results for these two types of geometrical inverse problems under certain situations.
