    "abstract": "A family of deformed Hopf algebras corresponding to the classical maximal\nisometry algebras of zero-curvature N-dimensional spaces (the inhomogeneous\nalgebras iso(p,q), p+q=N, as well as some of their contractions) are shown to\nhave a bicrossproduct structure. This is done for both the algebra and, in a\nlow-dimensional example, for the (dual) group aspects of the deformation.",
