Magnus Jiborn

A classical problem in political theory is how to explain unpopular and oppressive minority rule. How can a small minority manage to dominate a much larger population against its will? How come the oppressed majority does not revolt? Two rival approaches can be distinguished: the coordination theory, according to which the power of the minority rests on coordinated action among the minority and...

Parallel-in-time Magnus Integrators

Magnus integrators are a subset of geometric integration methods for the numerical solution of ordinary differential equations that conserve certain invariants in the numerical solution. This paper explores temporal parallelism of Magnus integrators, particularly in the context of nonlinear problems. The approach combines the concurrent computation of matrix commutators and exponentials within ...

Magnus expansions and beyond

In this brief review we describe the coming of age of Magnus expansions as an asymptotic and numerical tool in the investigation of linear differential equations in a Lie-group and homogeneous-space setting. Special attention is afforded to the many connections between modern theory of geometric numerical integration and other parts of mathematics: from abstract algebra to differential geometry...
