We find local closed-form expression for the Baker—Campbell—Hausdorff formula in the Lie algebra so(3), and interpret the formula geometrically in terms of rotation vectors in ℝ3. 
Closed Form of the Baker-Campbell-Hausdorff Formula for the Lie Algebra of Rigid Body Displacements
This paper demonstrates the existence of the closed form of the Baker-Campbell-Hausdorff (BCH) formula for the Lie algebra of rigid body displacement. For this, the structure of the Lie group of theExpand
The algebra of complex 2 × 2 matrices and a general closed Baker–Campbell–Hausdorff formula
We derive a closed formula for the Baker–Campbell–Hausdorff series expansion in the case of complex matrices. For arbitrary matrices A and B, and a matrix Z such that , our result expresses Z as aExpand
Baker–Campbell–Hausdorff–Dynkin Formula for the Lie Algebra of Rigid Body Displacements
The paper proposes, for the first time, a closed form of the Baker–Campbell–Hausdorff–Dynkin (BCHD) formula in the particular case of the Lie algebra of rigid body displacements. For this purpose,Expand

This article considers parameter‐dependent systems of reaction‐diffusion equations on the sphere, which are equivariant under the group $SO(3)$ of all rigid rotations on the Sphere, and gets the explicit characterization of these modulated rotating waves and all possible tip motions. Expand
On the relation between rotation increments in different tangent spaces
In computational mechanics, finite rotations are often represented by rotation vectors. Rotation vector increments corresponding to different tangent: spaces are generally related by a linearExpand
A variant of the inverted Lanczos method
In this note we study a variant of the inverted Lanczos method which computes eigenvalue approximates of a symmetric matrix A as Ritz values of A from a Krylov space of A−1. The method turns out toExpand
A geometric description of nonreciprocity in coupled two-mode systems
We explore the concept of nonreciprocity in coupled two-mode systems using a geometric mapping to the Poincare sphere. From this perspective, we recast the requirements for nonreciprocity in terms ofExpand

Using methods of control theory and some properties of rotations in three dimensions, it is proved that any nontrivial real 2-mode and "almost" any nontrevial real $3-mode beamsplitter is universal on $m\geq3$ modes. Expand

Lie-group methods
Many differential equations of practical interest evolve on Lie groups or on manifolds acted upon by Lie groups. The retention of Lie-group structure under discretization is often vital in theExpand
