The Universal Post-Lie-Rinehart Algebra of Planar Aromatic Trees
arXiv:2601.18528
Abstract
This paper defines the algebraic structure of tracial post-Lie-Rinehart algebras and describes the free object in this category. Post-Lie-Rinehart algebras is a generalisation of pre-Lie-Rinehart algebras, and of post-Lie algebroids.
