Gordan's lemma is a lemma in convex geometry and algebraic geometry. It can be stated in several ways. Let A be a matrix of integers. Let M be the set of non-negative integer solutions of A ⋅ x = 0 . Then there exists a finite subset of vectors in M , such that every element of M is a linear combination of these vectors with non-negative integer coefficients.
The semigroup of integral points in a rational convex polyhedral cone is finitely generated.
