A bare minimum on Rankin-Cohen brackets and deformation. I will do later an entry on related Jordanian twists, kind of Drinfeld twists (invertible counital 2-cocycles on bialgebras) which I worked on recently with collaborators in Zagreb. However, my new interest comes from a project in Hradec on geometry of foliations. Note that there are two Cohen’s in the subject – different initials are not typoi.
