Mathematics announced the decision of the main tasks of Geophysics Mathematician Andras washi from Stanford University (USA) announced the decision one of the most important problems of seismology — dimensional inverse kinematic problem. Performed in conjunction with two colleagues, as reported in the publication Nature News, scientists presented at a seminar held last week at University College London (UK). Three-dimensional inverse kinematic problem is a definition of high-speed characteristics of the environment known at the time of wave propagation along geodesic lines (shortest curves between two points in a metric space) with the known coordinates of the source and receiver. Scientists approach involves representation of the environment in which distributed indignation, in a kind of layers. Gradually determining the speed for each of them, the scientists were able, in their words, to prove the existence and uniqueness of the solution and also to obtain its explicit form in space dimension
