Convex Sets

  • Hoang Tuy
Part of the Nonconvex Optimization and Its Applications book series (NOIA, volume 22)


Let a, b be two points of R n. The set of all xR n of the form
$$x = \left( {1 - \lambda } \right)a + \lambda b = a + \left( {b - a} \right),\lambda \in R$$
is called the line through a and b. A subset M of R n is called an affine set (or affine manifold) if it contains every line through any two points of it, i.e. if (1 — λ)a + λbM for every aM, bM and every λ ∈ R. An affine set which contains the origin is a subspace.
