Noun
homothety (plural homotheties)
- (mathematics, geometry) An isotropic scaling transformation of an affine space with a single fixed point.
- 1972, Clayton W. Dodge, Euclidean Geometry and Transformations, 2004, page 106 ↗,
- One cannot obtain all similarity mappings from products of homotheties alone, but they are necessary and basic to similarities.
- 2011, Agustí Reventós Tarrida, Affine Maps, Euclidean Motions and Quadrics, Springer Undergraduate Mathematics Series, page 69 ↗,
- Since homotheties are determined by the fixed point, called the center of the homothety, and by the similitude ratio λ, we shall denote by hP,λ the homothety with center P and similitude ratio λ.
- 1972, Clayton W. Dodge, Euclidean Geometry and Transformations, 2004, page 106 ↗,
- (isotropic scaling transformation with a fixed point) homothecy, homogeneous dilation, homothetic transformation
- Italian: omotetia
