The many faces of projective objects


In mathematics and physics, there is quite a long list of objects which are, in some way, related to each other. It can be useful to keep down a little list of those various types of objects and their relationships.

Projective space

Probably the oldest such objects are the ones related to projective geometry.

Pl├╝cker coordinates

Quaternions

Quaternions are defined as an algebra over a $4$-dimensional vector space

Differential forms

Grassmann algebras

Spinors

Twistors
