I will do later an entry on related [[Jordanian twist]]s, 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 [[foliation]]s. Note that there are two Cohen's in the subject -- different initials are not typoi. <a href="https://ncatlab.org/nlab/revision/Rankin-Cohen+bracket/1">v1</a>, <a href="https://ncatlab.org/nlab/show/Rankin-Cohen+bracket">current</a>
