On interpolations between Jordanian twists

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 $\mathcal{; ; ; F}; ; ; _{; ; ; L, u}; ; ; $, we also show directly that the 2- cocycle condition reduces to previously proven identities.
