Abstract

We present a reconstruction method that stably recovers the real valued, symmetric tensors compactly supported in the Euclidean plane, from knowledge of their attenuated momenta ray transform. The problem is recast as an inverse boundary value problem for a system of transport equations, which we solve by an extension of Bukhgeim’s A-analytic theory. The method of proof is constructive. To illustrate the reconstruction method, we present results obtained in the numerical implementation for the non-attenuated case of one-tensors.

平面对称张量的衰减矩射线变换反演
我们提出了一种重构方法,它可以根据衰减矩射线变换的知识,稳定地恢复欧几里得平面内紧凑支撑的实值对称张量。这个问题被重构为一个传输方程系统的反边界值问题,我们通过布赫盖姆 A-analytic 理论的扩展来解决这个问题。证明方法是构造性的。为了说明重构方法,我们介绍了一张量非衰减情况下的数值计算结果。

期刊介绍: An interdisciplinary journal combining mathematical and experimental papers on inverse problems with theoretical, numerical and practical approaches to their solution. As well as applied mathematicians, physical scientists and engineers, the readership includes those working in geophysics, radar, optics, biology, acoustics, communication theory, signal processing and imaging, among others. The emphasis is on publishing original contributions to methods of solving mathematical, physical and applied problems. To be publishable in this journal, papers must meet the highest standards of scientific quality, contain significant and original new science and should present substantial advancement in the field. Due to the broad scope of the journal, we require that authors provide sufficient introductory material to appeal to the wide readership and that articles which are not explicitly applied include a discussion of possible applications.
