奇异系数Sturm-Liouville问题特征函数的振动性

On the oscillation properties of eigenfunctions of Sturm--Liouville problem with singular coefficients

A. A. Vladimirov

摘要:

本文考虑奇异谱Sturm-Liouville问题$-(py')'+(q-λr)y=0$,$(U-1)y^{\vee}+i(U+1)y^{\wedge}=0$,其中函数$p\in L_{\infty}[0,1]$是一致正的,广义函数$q,r\in W_2^{-1}[0,1]$是实值的,酉矩阵$U\in\mathbb C^{2\times 2}$是对角的.主要目的是证明众所周知的(光滑的情况下)的事实,在一般情况下举行的本征函数的零点的数量和分布。

英文摘要:

In the paper we consider singular spectral Sturm--Liouville problem $-(py')'+(q-λr)y=0$, $(U-1)y^{\vee}+i(U+1)y^{\wedge}=0$, where function $p\in L_{\infty}[0,1]$ is uniformly positive, generalized functions $q,r\in W_2^{-1}[0,1]$ are real-valued and unitary matrix $U\in\mathbb C^{2\times 2}$ is diagonal. The main goal is to prove that well-known (for smooth case) facts about number and distribution of zeros of eigenfunctions hold in general case.
