On Disconjugacy for Sturm-Liouville Difference Equations
We derive a Reid roundabout Theorem for Sturm-liouville Difference Equations of higher order by applying general results on linear Hamiltonian Difference Systems. This theorem gives conditions that are equivalent to the positive definiteness of a certain discrete quardratic functional among them disconjugacy of the related Sturm-Liouville Difference Equation and solvability of a certain discrete Riccati Matrix Equation.
