Spectral Asymptotics for Sturm-Liouville Equations
Proceedings of the London Mathematical Society, 1989The author gives a detailed interesting survey on asymptotic formulas for various spectral characteristics of the general Sturm-Liouville problem \(-(pu')'+qu=\lambda wu\) under very mild conditions on the coefficients p,q, and w. Such spectral quantities are, for instance, the eigenvalue distribution, Green's function, the spectral function, and the ...

Eigencurves for Two-Parameter Sturm-Liouville Equations
SIAM Review, 1996The authors study the two-parameter Sturm-Liouville eigenvalue problem \[ -(p(x)y')'+q(x)y=(\lambda r(x)+ \mu)y,\quad a\leq x\leq b \] with separated boundary conditions \[ \cos(\alpha)y(a)-\sin(\alpha)p(a)y'(a)= 0, \qquad \cos(\beta)y(b)-\sin(\beta)p(b)y'(b)=0, \] where \(p(x)\) is continuously differentiable and positive on \([a,b]\), and \(q\) and \(

Left-definite Sturm–Liouville equations
2020For this to be possible one needs some positivity in the problem, usually that some linear combination of the Hermitian forms is positive.

Preliminaries on Sturm-Liouville Equations
2020We will consider the second-order linear ordinary differential equation $$\displaystyle -y^{\prime \prime }+q(x)y=\lambda y $$ on a finite or infinite interval. This equation is called the Sturm-Liouville equation, or often the one-dimensional Schro dinger equation .

Abstract This chapter concerns the homogeneous equation where p : [a, b] → ℝ is continuously differentiable, q : [a, b] → ℝ and ⍴: [a, b] → ℝ are continuous, p(x) > 0 and ⍴(x) > 0, for all x in [a, b], and λ is a real constant.

The Periodic Sturm–Liouville Equations
2017We begin with a brief introduction the periodic Sturm–Liouville equations \([p(x)y'(x)]' + [\lambda w(x) - q(x)] y(x) = 0\). After reviewing some elementary knowledge of the theory of a general class of second-order linear homogeneous ordinary differential equations, we introduce two basic Sturm theorems on the zeros of solutions of the equations. Then,
