The existence of the Campbell–Baker–Hausdorff formula can now be seen as follows: The elements X and Y are primitive, so and are grouplike; so their product is also grouplike; so its logarithm ( ()) is primitive; and hence can be written as an infinite sum of elements of the Lie algebra … See more In mathematics, the Baker–Campbell–Hausdorff formula is the solution for $${\displaystyle Z}$$ to the equation If $${\displaystyle X}$$ and $${\displaystyle Y}$$ are … See more For many purposes, it is only necessary to know that an expansion for $${\displaystyle Z}$$ in terms of iterated commutators of $${\displaystyle X}$$ See more If $${\displaystyle X}$$ and $${\displaystyle Y}$$ are matrices, one can compute $${\displaystyle Z:=\log \left(e^{X}e^{Y}\right)}$$ using the power series for the exponential and logarithm, with convergence of the series if $${\displaystyle X}$$ See more • Matrix exponential • Logarithm of a matrix • Lie product formula (Trotter product formula) See more The formula is named after Henry Frederick Baker, John Edward Campbell, and Felix Hausdorff who stated its qualitative form, i.e. that only commutators and commutators of commutators, ad infinitum, are needed to express the solution. An earlier … See more If $${\displaystyle X}$$ and $${\displaystyle Y}$$ commute, that is $${\displaystyle [X,Y]=0}$$, the Baker–Campbell–Hausdorff formula reduces to $${\displaystyle e^{X}e^{Y}=e^{X+Y}}$$.
