It is shown that simple shooting and a standard iterative technique, e.g. Newton's method, applied to a regular elliptic Sturm-Liouville boundary value problem form a chaotic dynamical system. We then develop and apply an action-angle modification of the Prufer substitution based on a Hamiltonian formalism which, when applied to the transformed Sturm-Liouville system, eliminates the chaotic set and ensures convergence of the Newton iterates. A further generalization of the Prufer modified transformation leads to a class of higher order heuristic methods for integrating Sturm-Liouville equations.


Membership to CARMA offers many benefits and is available by invitation to all University of Newcastle academic staff. Associate membership, also by invitation, is available to external researchers and practitioners for three-year renewable terms. Associate members are expected to visit CARMA with some frequency, typically for a total of three to four weeks in a year, and to be involved in one or more ongoing research projects with CARMA members. CARMA is able to assist with the travel and living costs of such visits.
