Description
The Jordan plane, a well-known deformation of the polynomial ring in 2 variables, has a structure of braided Hopf algebra and as such, it has various associated Hopf algebras, varying with the characteristic of the base field. I will report on recent work on these Hopf algebras, jointly with Héctor Peña Pollastri and François Dumas.
