# A note on a paper of Harris concerning the asymptotic approximation to the eigenvalues of -y''+qy=\lambda y, with boundary conditions of general form Artikel i vetenskaplig tidskrift, 2012

In this paper, we derive an asymptotic approximation to the eigenvalues of the linear differential equation $$-y''(x)+q(x)y(x)=\lambda y(x),\hskip 1.4 true cm x\in (a,b)$$ with boundary conditions of general form, when $q$ is a measurable function which has a singularity in $(a,b)$ and which is integrable on subsets of $(a,b)$ which exclude the singularity.
