耦合Wave Equations系数反问题的对数稳定性

Logarithmic Stability for Coefficients Inverse Problem of Coupled Wave Equations

Fangfang Dou, Masahiro Yamamoto

摘要:

本文研究了一个耦合双曲型方程组的两个系数的识别问题。在耦合波方程Carleman估计的基础上,假设系数在某个子边界的邻域内给定,仅在适当选取的子域内由测量数据得到了对数型稳定性结果.

英文摘要:

This paper investigates the identification of two coefficients in a coupled hyperbolic system with an observation on one component of the solution. Based on the the Carleman estimate for coupled wave equations a logarithmic type stability result is obtained by measurement data only in a suitably chosen subdomain under the assumption that the coefficients are given in a neighborhood of some subboundary.
