Abstract

This paper studies a class of singular differential equations
$$\begin{aligned} -\left( \frac{\mathrm {d}}{{\mathrm {d}}x}-\frac{k}{x^{l}}-v\right) \left( \frac{{\mathrm {d}}}{{\mathrm {d}}x}+\frac{k}{x^{l}}+v\right) y=\lambda y \text { on }J=(0,1) , \end{aligned}$$
where \(k\ge \frac{1}{2},1\le l<2\) and \(v\in L^{1}(J, {\mathbb {R}} )\) which is bounded below. Using the prüfer transformation, we get the oscillation property of the eigenfunctions. In particular, the location of eigenvalues are also described. Furthermore, we establish the continuous dependence of nth eigenvalue on the boundary condition.
