16 июн. 2010 г. · The proof presented is based on the group property of U, and conceals all the mathematical subtleties in a simplified form of the BCH formula.

Proof. The proof, based on Magnus' expansion, is deferred until appendix C. The following is an easy-to-prove sufficient condition for commutativity. Lemma ...

3 янв. 2013 г. · In the previous lecture, we proved the Chen's expansion formula which establishes the fact that the signature of a path is the exponential of a Lie series.

First, we present Magnus's theorem. 6.1 Magnus expansion. This exposition and proof sketch of Magnus's theorem is my own. My conceptual contribution here.

This relationship between the infinite series and binary trees leads both to a convergence proof and to constructive computational algorithm. This numerical ...

The Magnus expansion furnishes an elegant setting to build up approximate exponential representations of the solution of the system.

Since the 1960s, the Magnus expansion has been successfully applied as an analytic tool in numerous areas of physics and chemistry, from nuclear, atomic and ...
