内容説明

01/07 This title is now available from Walter de Gruyter. Please see www.degruyter.com for more information. This book surveys basic features of the comparatively newly emerged theory of inverse problems for equations of mathematical physics, i.e. of the problems aimed at defining the coeficients of a differential equation through some functionals of its solution. This kind of problem arises in various fields of science when trying to describe internal characteristics of a substance where physico-chemical processes take place by the results of observing these processes within the available range of measurements. The book offers in-depth coverage of inverse problems for second-order equations and for hyperbolic systems of first-order equations, including the kinematic problem of seismology, the Lamb dynamic problem for equations of the theory of elasticity, and the problem of electrodynamics.
