Explicit Baker-Campbell-Hausdorff formulae for some specific Lie algebras

Alexander Van-Brunt, Matt Visser

In a previous article, [arXiv:1501.02506, JPhysA {\bf48} (2015) 225207], we demonstrated that whenever $[X, Y] = u X + v Y + c I$ the Baker-Campbell-Hausdorff formula reduces to the t…

Simplifying the Reinsch algorithm for the Baker-Campbell-Hausdorff series

Alexander Van-Brunt, Matt Visser

The Baker-Campbell-Hausdorff series computes the quantity \begin{equation*} Z(X,Y)=\ln\left( e^X e^Y \right) = \sum_{n=1}^\infty z_n(X,Y), \end{equation*} where $X$ and $Y$ are not…

Special-case closed form of the Baker-Campbell-Hausdorff formula

Alexander Van-Brunt, Matt Visser

The Baker-Campbell-Hausdorff formula is a general result for the quantity $Z (X, Y) = ln (e^{X} e^{Y})$ , where $X$ and $Y$ are not necessarily commuting. For completely general commutati…
