Анотація

Approximation of nonlinear geophysical medium as a linear one substantiates a transition to geometrical seismics based on geometric optics. Conditions, necessary and sufficient for application of geometrical optics bring possibility of linearization  the eikonal equation and produce two approaches in the problems of seismic tomography: a classical Lavrentyev— Romanov linearization  and the Taylor approximation.
