Convergence of Lie group integrators
(Journal article; Peer reviewed, 2019)We relate two notions of local error for integration schemes on Riemannian homogeneous spaces, and show how to derive global error estimates from such local bounds. In doing so, we prove for the first time that the Lie–Butcher ... -
