(mathematics)
Point coordinates and plane coordinates are dual in geometry since an equation about one determines an equation about the other.

The resulting noncommutative space-times show how the curvature modifies the underlying first-order [kappa]-Minkowski space, while for the noncommutative spaces of worldlines we find that 2D velocity/rapidity space (spanned by the dual coordinates to the boost generators) remains nondeformed for [kappa]-Poincare but becomes deformed for the (A)dS cases.
