21Special affine group — In the mathematical study of transformation groups, the special affine group is the group of affine transformations of a fixed affine space which preserve volume.On Rn, every special affine transformation has the form:mathbf{x}mapsto… …
22Ehlers group — In mathematical physics, the Ehlers group, named after Jürgen Ehlers, is a finite dimensional transformation group of stationary vacuum spacetimes which maps solutions of Einstein s field equations to other solutions. It has since found a number… …
23Symmetry group — Not to be confused with Symmetric group. This article is about the abstract algebraic structures. For other meanings, see Symmetry group (disambiguation). A tetrahedron can be placed in 12 distinct positions by rotation alone. These are… …

28Natural transformation — This article is about natural transformations in category theory. For the natural competence of bacteria to take up foreign DNA, see Transformation (genetics). In category theory, a branch of mathematics, a natural transformation provides a way… …
29Projective transformation — A projective transformation is a transformation used in projective geometry: it is the composition of a pair of perspective projections. It describes what happens to the perceived positions of observed objects when the point of view of the… …
30Affine transformation — In geometry, an affine transformation or affine map or an affinity (from the Latin, affinis , connected with ) between two vector spaces (strictly speaking, two affine spaces) consists of a linear transformation followed by a translation::x… …
