Alexander Katchalov, Yaroslav Kurylev, Matti Lassas, Niculae Mandache

摘要:

我们考虑波,热和薛定谔型算子的反问题和相应的谱问题的区域上的${\bf R}^n$和紧流形。此外,我们还研究了反问题,其中的系数部分微分算子已被发现时,一个人知道有多少能量,它是需要强制的解决方案,有给定的边界值,即,人们知道进行给定测量需要多少能量。本文的主要结果是表明,所有这些问题是等价的。

英文摘要:

We consider inverse problems for wave, heat and Schrödinger-type operators and corresponding spectral problems on domains of ${\bf R}^n$ and compact manifolds. Also, we study inverse problems where coefficients of partial differential operator have to be found when one knows how much energy it is required to force the solution to have given boundary values, i.e., one knows how much energy is needed to make given measurements. The main result of the paper is to show that all these problems are shown to be equivalent.
