在这项工作中,我们分析了声波方程的参数-解映射与它的参数波速和质量密度。这张图是地震反演问题的数学模型,其中人们希望从声势的测量中恢复参数。证明了它的完全连续性和可微性。为此,我们提供了必要的存在性、稳定性和规律性结果。此外,我们还讨论了我们的发现对逆问题的各种含义,并对玻恩系列进行了评论。版权所有©2013 John Wiley & Sons, Ltd
In this work, we analyze the parameter‐to‐solution map of the acoustic wave equation with respect to its parameters wave speed and mass density. This map is a mathematical model for the seismic inverse problem where one wants to recover the parameters from measurements of the acoustic potential. We show its complete continuity and Fréchet differentiability. To this end, we provide necessary existence, stability, and regularity results. Moreover, we discuss various implications of our findings on the inverse problem and comment on the Born series. Copyright © 2013 John Wiley & Sons, Ltd.
