Affine set definition
WebMar 24, 2024 · An affine transformation is any transformation that preserves collinearity (i.e., all points lying on a line initially still lie on a line after transformation) and ratios of distances (e.g., the midpoint of a line segment remains the midpoint after transformation). In this sense, affine indicates a special class of projective transformations that do not move … WebMar 24, 2024 · In an affine space, it is possible to fix a point and coordinate axis such that every point in the space can be represented as an -tuple of its coordinates. Every ordered pair of points and in an affine space is then associated with a vector . See also

WebApr 4, 2024 · In algebraic geometry an affine algebraic set is sometimes called an affine space. A finite-dimensional affine space can be provided with the structure of an affine variety with the Zariski topology (cf. also Affine scheme ). Affine spaces associated with a vector space over a skew-field $ k $ are constructed in a similar manner. References [1] WebAnswer (1 of 2): Recall that a set is affine if, whenever it contains the elements a and b, it also contains the elements (1 - t)a + tb for any t \in \mathbb{R}. It follows immediately that every vector space is an affine set, but there are other examples as well. Let V be some vector space, let ...

An affine scheme is a locally ringed space isomorphic as a locally ringed space to for some ring . A morphism of affine schemes is a morphism in the category of locally ringed spaces. It turns out that affine schemes play a special role among all locally ringed spaces, which is what the next section is about.
