Реферат: The travel time tomography problem is a coefficient inverse problem for the eikonal equation. Applications of this problem in the field of seismology are well known. The eikonal equation is considered here in the circular cylinder, where point sources run along its axis and measurements of travel times are conducted on the whole surface of this cylinder. A new version of the globally convergent convexification numerical method for this problem is developed. Results of numerical studies are presented.
