Abstract: | Summary. The collocation tension spline is considered as a numerical solution of a singularly perturbed two-point boundary value problem:
. The collocation points are chosen as a generalization of the classical Gaussian points. Unlike the traditional approach,
we employ the B-spline representation in the analysis. This leads to global quadratic convergence of the method for small
perturbation parameters, and, for large values, the order of convergence is four.
