Magnus series expansion method
Web3 jan. 2016 · In this paper, the differential equation for the motion of a mass on a spring is investigated, solutions of six different cases were analyzed and numerical solutions are obtained by means of Magnus Expansion Method. Any truncation of the Magnus series preserves qualitative geometric properties of the exact solution (Castellano et al. 2014). WebThe goal of this review is threefold. First, to collect a number of developments scattered through half a century of scientific literature on Magnus expansion. They concern the methods for the generation of terms in the expansion, estimates of the radius of convergence of the series, generalizations and related non-perturbative expansions.
