document: Extrapolation in Lie groups with approximated BCH-formula We present an extrapolation algorithm for the integration of differential equations in Lie groups which is a suitable generalization of the well-known GBS-algorithm for ODEs . Sufficiently accurate approximations to the BCH-formula are required to reach a given order . We give such approximations with a minimized number of commutators
