关于位势分布的Sturm-Liouville算子的特征函数

On the eigenfunctions of Sturm--Liouville operators with potentials --- distributions

Artem Savchuk

摘要:

本文研究了空间$L_2[0,π]$中具有Direchlet边界条件的Sturm-Liouville算子$Ly=-y"+q(x)y$.这里,潜在的$q$是一阶分布:$q\in W_2^{-1}[0,π]$。这些算子在我们以前的论文中已经定义过了。本文阐明了这类算子的本征函数和双正交系函数的渐近公式中的两个首项。

英文摘要:

In this paper we study a Sturm--Liouville operator $Ly=-y"+q(x)y$ in the space $L_2[0,π]$ with Direchlet boundary conditions. Here the potential $q$ is a first order distribution: $q\in W_2^{-1}[0,π]$. Such operators were defined in our previous papers. Here we clerify two leading terms in asymptotic formulae for eigenfunctions of such operators and for functions of biorthogonal system.
