具有不完全散射数据的直线上的逆散射

Inverse scattering on the line with incomplete scattering data

Tuncay Aktosun

摘要:

薛定谔方程被认为是在线时的潜力是实值,紧支持,平方可积。从相应的反射系数与透射系数之比组成的数据中,分析了恢复这种电位的非唯一性。结果表明,有一个离散的数量的潜力,相应的数据和他们的L^2-范数是相互关联的,在一个简单的方式。所有这些势都被识别出来了,并且展示了如何在数据中对L^2范数进行额外的估计来唯一地识别相应的势。恢复说明了一些明确的例子。

英文摘要:

The Schroedinger equation is considered on the line when the potential is real valued, compactly supported, and square integrable. The nonuniqueness is analyzed in the recovery of such a potential from the data consisting of the ratio of a corresponding reflection coefficient to the transmission coefficient. It is shown that there are a discrete number of potentials corresponding to the data and that their L^2-norms are related to each other in a simple manner. All those potentials are identified, and it is shown how an additional estimate on the L^2-norm in the data can uniquely identify the corresponding potential. The recovery is illustrated with some explicit examples.
