Abstract
On determining the index of refraction in anisotropic media

Abstract: We survey recent results on the inverse kinematic problem
arising in geophysics. The question is whether one can determine the sound
speed (index of refraction) of a medium by measuring the travel times of
the corresponding ray paths. We emphasize the anisotropic case.
