Description
We study four-dimensional κ-Minkowski spacetime constructed by the twist deformation of U(igl(4,R)). We demonstrate that the differential structure of such twist-deformed κ-Minkowski spacetime is closed in four dimensions contrary to the construction of κ-Poincare bicovariant calculus which needs an extra fifth dimension. Our construction holds in arbitrary dimensional spacetimes
