Projective Space
A Space which is invariant under the Group 
of all general Linearhomogeneous transformation in the Space concerned, but not under all the transformations of any Groupcontaining as a Subgroup.
A projective space is the space of 1-D VectorSubspaces of a given Vector Space. For Real Vector Spaces, theNotation 
or 
denotes the Real projective space of dimension 
(i.e., the Space of1-D Vector Subspaces of 
) and 
denotes the Complexprojective space of Complex dimension (i.e., the space of 1-D Complex VectorSubspaces of 
). can also be viewed as the set consisting of 
together with its Points at Infinity.
