摘要
我们提供了一种新的方法来建立与Sturm-Liouville微分算子的Titchmarsh-Weyl m-函数相关的Simon's a -函数。该方法基于与转换算子核的连接。我们还得到了有限区间上a函数的一些性质,从而得到了Titchmarsh-Weyl m函数的高能渐近表示。
The A-function related to the Titchmarsh-Weyl m-function of Sturm-Liouville operators
We provide a new method to establish Simon's A-functions associated with the Titchmarsh-Weyl m-functions of Sturm-Liouville differential operators. This method is based on a connection with the kernel of transformation operators. We also obtain some properties of the A-functions on finite intervals, which yield a high-energy asymptotic representation of the Titchmarsh-Weyl m-function.
