Jacobi矩阵的求和规则及其在谱理论中的应用

Sum Rules for Jacobi Matrices and Their Applications to Spectral Theory

Rowan Killip, Barry Simon

摘要:

讨论了雅可比矩阵凯斯求和规则的证明及其系统应用。特别感兴趣的是一个线性组合的两个他的总和规则,其中有严格的积极条款。我们的结果包括对J-J_0是Hilbert-Schmidt的Jacobi矩阵J的谱测度的完全分类,以及证明了Nevai猜想:当J-J_0是迹类时,Szego条件成立。

英文摘要:

We discuss the proof of and systematic application of Case's sum rules for Jacobi matrices. Of special interest is a linear combination of two of his sum rules which has strictly positive terms. Among our results are a complete classification of the spectral measures of all Jacobi matrices J for which J-J_0 is Hilbert--Schmidt, and a proof of Nevai's conjecture that the Szego condition holds if J-J_0 is trace class.
