WebOct 7, 2024 · In this paper an explicit formula for the computation of common denominators for the rational coefficients of the homogeneous components of the series is derived. Explicit computations up to degree 30 show that the common denominators obtained by this formula are as small as possible, which suggests that the formula is in a sense optimal.

Web1 Baker-Hausdorff 公式是一个相当有用的公式。 在数学上，它可用于给出李群-李代数对应的深层结果的相对简单的证明；在量子力学中，它可实现系统哈密顿量在薛定谔绘景和 … WebThen. t y) = e s x e t y f = e b ( s x, t y) f. By 1., we must have β ~ ( s x, t y) = b ( s x, t y) as formal power series. But β ~ is the Taylor expansion of the analytic function β. Thus in a small enough neighborhood of the origin, it converges. By definition, β ~ = b is the Baker–Campbell–Hausdorff series.
