Disconjugacy of functional and differential systems (associated with input-output scattering model)
In this paper, we present disconjugacy properties of a functional equation or the associated differential system from the input-output point of view. These functional equations or differential systems play a major role in transport systems. Our main result was that such a system had a unique solution under a stated if and only if condition.
