Lorentz transformation
(mathematics, relativity) A transformation relating the spacetime coordinates of one frame of reference to another in special relativity.
affine transformation
(geometry, linear algebra) A geometric transformation that preserves lines and parallelism, but in general not lengths or angles; (more formally) an automorphism of an affine space: a mapping of an affine space onto itself that preserves both the dimension of any affine subspace and the ratio of the lengths of any pair of parallel line segments.
integral transforms
Laplace transforms
Tschirnhaus transformation
(mathematics) A type of mapping on polynomials that may be defined by means of field theory as the transformation on minimal polynomials implied by a different choice of primitive element.
Tschirnhaus transformations
Tschirnhausen transformations
Möbius transformation
(geometry, complex analysis) A transformation of the extended complex plane that is a rational function of the form f(z) = (az + b) / (cz + d), where a, b, c, d are complex numbers such that ad − bc ≠ 0; an automorphism of the complex projective line.
