Bch formula wikipedia
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. WebBaker{Campbell{Hausdor formula is sometimes known as Dynkin’s formula. Remark 2.4. The Zgiven by the Baker{Campbell{Hausdor formula may not ac-tually converge to an …

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? WebJul 7, 2024 · The BCH formula is used in Physics extensively, especially in the cases where Schrodinger dynamics is involved. – user123 Jul 7, 2024 at 16:10 1 Normally, in QM one applies the degenerate CBH formula, where the commutator is central, and so higher orders are trivial or simple.
