Baker–Campbell–Hausdorff formula: History & Applications

In mathematics, the Baker–Campbell–Hausdorff formula gives a value of Z {\displaystyle Z} that solves the equation e X e Y = e Z {\displaystyle e^{X}e^{Y}=e^{Z}} for possibly noncommutative X and Y in the Lie algebra of a Lie group. There are various ways of writing the formula, but all ultimately yield an expression for Z {\displaystyle Z} in Lie…
