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

Mahdi Hormozi

In this paper, we derive an asymptotic approximation to the eigenvalues of the linear differential equation $$-y"(x)+q(x)y(x)=\lambda y(x),x\in (a,b)$$ with boundary conditions of gene…
