On interpolations between Jordanian twists
Abstract
We consider two families of Drinfeld twists generated from a simple Jordanian twist further twisted with 1-cochains. Using combinatorial identities, they are presented as a series expansion in the dilatation and momentum generators. These twists interpolate between two simple Jordanian twists. For an expansion of a family of twists FL,u, we also show directly that the 2-cocycle condition reduces to previously proven identities.
