Numerical determination of the Titchmarsh-Weyl m-coefficient
Abstract
A numerical method for calculating the Titchmarsh-Weyl mα(λ)-coefficient for the differential equation d2y/dx2+ [1 - q(x)]y = 0 is tested for the cases q(x) = x and x2, for which mα(λ) has a known analytic form in terms of special functions. An independent assessment of the accuracy of our results using the analytical solution for mα(λ) and a previous numerical method enables us to demonstrate the high accuracy of our calculation.
