Microlocal Methods for The Elastic Travel Time Tomography Problem for Transversely Isotropic Media [PDF]

arXiv, 2021
We study the travel time tomography problem for transversely isotropic media using the artificial boundary method used in works in X-ray tomography and boundary rigidity problems. The analysis involved requires a modification of the scattering pseudodifferential calculus in order to provide parametrices for operators which are degenerately elliptic ...
