	Categories: Number theory Heegner number In number theory, a Heegner number is a positive integer n such that the quadratic field $Q(\sqrt{-n})$ has class number 1. Equivalently, its ring of integers has unique factorization. See Stark-Heegner theorem for the proof that such n that are square free are finite in number.
