WebThe Baker-Campbell-Hausdorff (BCH) formula for the 3-dimensional rotations can indeed be summed up. Here we will just state the result in the notation of Ref. 1. Three-dimensional rotations are described by the Lie group SO(3). The corresponding Lie algebra so(3) is [Lj, Lk] = i 3 ∑ ℓ = 1ϵjkℓLℓ, j, k, ℓ ∈ {1, 2, 3}, ϵ123 = 1, i2 = − 1. http://staff.ustc.edu.cn/~yhbao/2024_Operad/Slides/Sun-Baker-Campbell-Hausdorff%20formula%20revisited.pdf

WebA simple algorithm, which exploits the associativity of the BCH formula, and that can be generalized by iteration, extends the remarkable simplification of the Baker-Campbell-Hausdorff (BCH) formula, recently derived by Van-Brunt and Visser. We show that if [X,Y] = uX+vY +cI, [Y,Z] = wY +zZ+dI, and, consistently with dr. robert cash modesto ca

WebSep 26, 2024 · Under the "Special cases" section, there is a notation log ( e X e Y) = X + ad X 1 − e − ad X Y + O ( Y 2), but it doesn't provide a reference for this formula. Who discovered this representation of the BCH formula and does it hold in the general case for general X and Y or is this only valid in the case [ X, Y] = s Y?
