摘要:

本文首次证明了n维Helmholtz方程在多个波数下逆源问题的递增稳定性,这与二维或三维Helmholtz方程的情形不同。此外,我们提出了一种新的统一方法来研究任意维度下的递增稳定性。该方法基于Fourier变换和解析延拓的显式界。

英文摘要:

In this paper, we show for the first time the increasing stability of the inverse source problem for the n-dimensional Helmholtz equation at multiple wave numbers, which is different from the two-or three-dimensional Helmholtz equation. In addition, we develop a new, unified approach to study increasing stability in any dimension. The method is based on the Fourier transform and explicit bounds for analytic continuation.
