Campbell baker hausdorff 公式
WebDec 10, 2024 · Abstract. An exact representation of the Baker–Campbell–Hausdorff formula as a power series in just one of the two variables is constructed. Closed form coefficients of this series are found in terms of hyperbolic functions, which contain all of the dependence on the second variable.
