Jacobi矩阵的相对振动理论

Relative Oscillation Theory for Jacobi Matrices

Kerstin Ammann, Gerald Teschl

摘要:

我们发展了Jacobi矩阵的相对振动理论,它不是计算一个矩阵的特征值的个数,而是计算两个不同矩阵的特征值个数之差。这是通过将与一个矩阵相关联的解的节点替换为两个不同矩阵的解的朗斯基函数的加权节点来完成的。

英文摘要:

We develop relative oscillation theory for Jacobi matrices which, rather than counting the number of eigenvalues of one single matrix, counts the difference between the number of eigenvalues of two different matrices. This is done by replacing nodes of solutions associated with one matrix by weighted nodes of Wronskians of solutions of two different matrices.
