关于二阶finite-difference算子的一个反问题

On an inverse problem for finite-difference operators of second order

Mikhail Kudryavtsev

摘要:

考虑重数为2的谱与其单谱分离且包含一个绝对连续谱区间的有界Jacobi矩阵。一种新的类型的光谱数据,这是类似的散射数据,介绍了这个矩阵。一个积分方程,使我们能够重建矩阵,从这个光谱数据获得。我们用这个方程来解决Toda格点的Cauchy问题,初始数据是不稳定的。

英文摘要:

The Jacobi matrices with bounded elements whose spectrum of multiplicity 2 is separated from its simple spectrum and contains an interval of absolutely continuous spectrum are considered. A new type of spectral data, which are analogous for scattering data, is introduced for this matrix. An integral equation that allows us to reconstruct the matrix from this spectral data is obtained. We use this equation to solve the Cauchy problem for the Toda lattice with the initial data that are not stabilized.
