This article is devoted to the 100 year anniversary of Georgy Pertashen, a founder of Laboratory of Elastic Media Dynamics of at Leningrad State University and presents an adapted version of the first chapter of [Петрашень and Нахамкин, 1973]. This topic has been selected due to the wide interest of geophysicists in the migration problem and continuation of wave fields that has kept growing in the last 30 years. In [Петрашень, Нахамкин, 1973] the authors for the first time gave the clear mathematical problem statement of wave field continuation and laid the grounds of many migration methods that are widely applied today. The publication has been one of the engines that boosted the advance of Soviet (Russian) Theoretical Geophysics, if compared with the well-known and highly cited monograph by Сlaerbout . The one by G.I. Petrahsen, S.A. Nakhamkin had been published in 1973 and has now been a rarity, so it’s essential to attract attention of the young generation of geophysics to it. For the book is not only written in very good language, but also contains detailed explanations of the physics and possible applications for all the calculations given.
