流形上反问题中的非对易几何元素

Elements of noncommutative geometry in inverse problems on manifolds

M. I. Belishev, M. N. Demchenko

摘要:

本文讨论了两个与带边界的黎曼流形相联系的动力系统。第一个是由标量波动方程控制的系统,第二个是由麦克斯韦方程组控制的系统。这两个系统都是从边界控制的。逆问题是通过边界处的相关测量(逆数据)来恢复流形。我们证明了逆数据决定了一个C*-代数,其(拓扑化)谱与流形相同。由此,恢复流形就是从逆数据中确定一个适当的代数,找到它的谱,并提供具有黎曼结构的谱。本文发展了一种代数版本的边界控制方法,这是一种方法,反问题的基础上,他们的关系,控制理论。

英文摘要:

We deal with two dynamical systems associated with a Riemannian manifold with boundary. The first one is a system governed by the scalar wave equation, the second is governed by the Maxwell equations. Both of the systems are controlled from the boundary. The inverse problem is to recover the manifold via the relevant measurements at the boundary (inverse data). We show that the inverse data determine a C*-algebras, whose (topologized) spectra are identical to the manifold. By this, to recover the manifold is to determine a proper algebra from the inverse data, find its spectrum, and provide the spectrum with a Riemannian structure. The paper develops an algebraic version of the boundary control method, which is an approach to inverse problems based on their relations to control theory.
