adjective Invariant under projective transformations.
adjective Defined in or inhabiting a projective space.
adjective In a technical sense, general (but not necessarily so general as to be free); involving such objects: Such that there is another (left) R-module N with M⊕N a free R-module. Equivalently, projective in the category of modules (see below). Such that, given an epimorphism e:E→X and morphism f:P→X, f factors through e; that is, there exists a morphism f~:P→E with e∘f~=f. Such that every epimorphism from a profinite group onto G has a right inverse which is a homomorphism. Such that every object in the resolution is projective.
