About LieGroups.jl

The package LieGroups.jl in its current form started in 2024 as a “spin-off” from Manifolds.jl, where a type GroupManifolds was a predecessor of the main LieGroup type of this package. That approach started around 2021 by Seth Axen. At about the same, Yueh-Hua Tu started a package LieGroups.jl, which was continued then here with a full rewrite in order to base all Lie groups on a manifold from Manifolds.jl.

The current main developers are Ronny Bergmann and Mateusz Baran.
