projective plane

<mathematics> The space of equivalence classes of vectors under non-zero scalar multiplication. Elements are sets of the form

	{kv: k != 0, k scalar, v != O, v a vector}

where O is the origin. v is a representative member of this equivalence class.

The projective plane of a vector space is the collection of its 1-dimensional subspaces. The properties of the vector space induce a topology and notions of smoothness on the projective plane.

A projective plane is in no meaningful sense a plane and would therefore be (but isn't) better described as a "projective space".
