Minkowski's TheoremIn mathematics, Minkowski's theorem in the geometry of numbers applies to convex symmetric sets and lattices; it relates the number of contained lattice points to the volume of such a set. This relationship was discovered by Hermann Minkowski in 1889. Let L be a lattice in Rn with determinant d(L). The simplest example is the lattice Zn of all points with integer coefficients; its determinant is 1. Consider a convex subset S of Rn that is symmetric with respect to the origin, meaning that x in S implies −x in S. Minkowski's theorem states that if the volume of S is bigger than 2nd(L), then S must contain at least 3 lattice points (the origin, another point, and its negative).
