WebNote. As the reader may know, a function with increasing derivative is convex (infor-mally, this means curving upwards). So logΓ(x) is convex. The celebrated Bohr-Mollerup theorem states that the gamma function is the unique function f(x) with the property that logf(x) is convex, together with f(x+1) = xf(x) and f(1) = 1.
