Nonlinear discrete Sturm–Liouville problems

open access: yesJournal of Mathematical Analysis and Applications, 2005
The paper is devoted to discrete boundary value problems of the form \[ \Delta\left[ p\left( t-1\right) \Delta y\left( t-1\right) \right] +q\left( t\right) y\left( t\right) +\lambda y\left( t\right) =f\left( y\left( t\right) \right) , \] \(t=a+1,\dots,b+1,\) subject to the boundary conditions \[ a_{11}y\left( a\right) +a_{12}\Delta y\left( a\right) =0,\

The SLEIGN2 Sturm-Liouville code

open access: yes, 1998
. The SLEIGN2 code is based on the ideas and methods of the original SLEIGN code of 1979. The main purpose of the SLEIGN2 code is to compute eigenvalues and eigenfunctions of regular and singular self-adjoint Sturm-Liouville problems, with both separated

Inverse spectral problems for nonlinear Sturm-Liouville problems

open access: yesElectronic Journal of Differential Equations, 2007
This paper concerns the nonlinear Sturm-Liouville problem $$ -u''(t) + f(u(t)) = lambda u(t), quad u(t) > 0, quad t in I := (0, 1), quad u(0) = u(1) = 0, $$ where $lambda $ is a positive parameter. We try to determine the nonlinear term $f(u)$ by means
