We show that, if there exists a realization of a Hopf algebra H in a H-module algebra , then one can split their cross-product into the tensor product algebra of itself with a subalgebra isomorphic to H and commuting with . This result applies in particular to the algebra underlying inhomogeneous quantum groups like the Euclidean groups, which are obtained as cross-products of the quantum Euclidean spaces qN with the quantum groups of rotation Uq so(N) of qN, for which it has no classical… Expand
Decoupling of Translations from Homogeneous Transformations in Inhomogeneous Quantum Groups

More examples of invariance under twisting
The so-called “invariance under twisting” for twisted tensor products of algebras is a result stating that, if we start with a twisted tensor product, under certain circumstances we can “deform” theExpand
