sudgylacmoe | The Logarithm of a Rotor @sudgylacmoe | Uploaded September 2024 | Updated October 2024, 2 hours ago.
Last week, I talked about how to interpolate rotors. But to do that, you need to know how to exponentiate bivectors and find the logarithm of rotors! I covered the exponentiation part a while ago: youtube.com/shorts/YnzQBC5zx9U. In this short, I show how to calculate logarithms of rotors.

The idea in this short is based on a paper by Roelfs and De Keninck, and a preprint for the paper, including algorithms for finding these simple commuting decompositions, can be found here: arxiv.org/abs/2107.03771
