Definition df-mapd 38755

Description: Extend class notation with a one-to-one onto (mapd1o 38778), order-preserving (mapdord 38768) map, called a projectivity (definition of projectivity in [Baer] p. 40), from subspaces of vector space H to those subspaces of the dual space having functionals with closed kernels.
