DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Inverse/44/"
 >Travel time tomography in stationary spacetimes</a>\nby Hanming Zhou (UC 
 Santa Barbara) as part of International Zoom Inverse Problems Seminar\, UC
  Irvine\n\n\nAbstract\nIn this talk\, I will discuss the boundary rigidity
  problem on a cylindrical domain in $\\mathbb R^{1+n}$\, $n\\geq 2$\, equi
 pped with a stationary (time-invariant) Lorentzian metric. We show that th
 e time separation function between pairs of points on the boundary of the 
 cylindrical domain determines the stationary spacetime\, up to some time-i
 nvariant diffeomorphism\, assuming that the metric is close to the Minkows
 ki metric\, and satisfies some a-priori conditions. The talk is based on j
 oint work with Gunther Uhlmann (UW) and Yang Yang (MSU).\n
