摘要:

我们建立了从部分Dirichlet到Neumann映射确定Helmholtz方程势的三对数稳定性估计,在高频极限下。该估计是在假设当维度大于等于3时,势在域边界附近已知的条件下证明的。此外,我们还展示了对于内部阻抗问题的三对数稳定性。

英文摘要:

We establish a triple logarithmic stability estimate of determining the potential in a Helmholtz equation from a partial Dirichlet-to-Neumann map in the high frequency limit. This estimate is proved under the assumption that the potential is known near the boundary of a domain when the dimension is greater than or equal to $3$. In addition, we show a triple logarithmic stability for an interior impedance problem.
