Affine set definition
WebDe nition 1. A set is called \a ne" i for any two points in the set, the line through them is contained in the set. In other words, for any two points in the set, their a ne combinations are in the set itself. Theorem 1. A set is a ne i any a ne combination of points in the set is in the set itself. Proof. Exercise. (Use induction) Exercise 2. WebJul 13, 2024 · Definition: Affine Plane. A (finite) affine plane consists of a (finite) set of points, a (finite) set of lines, and an incidence relation between the points and the lines.The incidence relation must satisfy these Euclidean axioms: Any two points lie together on a unique line. For any line \(L\), and any point \(p\) that does not lie on the line \(L\), there is …

From the definition of affine sets, we can similarly guess the definitionof convex sets. Definition 2 set is called convex iff any convex combination of a subset is also contained in the set itself.
WebMar 24, 2024 · Affine The adjective "affine" indicates everything that is related to the geometry of affine spaces. A coordinate system for the -dimensional affine space is determined by any basis of vectors, which are not necessarily orthonormal. Therefore, the resulting axes are not necessarily mutually perpendicular nor have the same unit measure. 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
