His name is sometimes transliterated as Kusmin. In 1928, Kuzmin solved the following problem due to Gauss (see Gauss–Kuzmin distribution): if x is a random number chosen uniformly in (0, 1), and C,α > 0 are numerical constants. In 1930, Kuzmin proved that numbers of the form ab, a is algebraic and b is a real quadratic irrational, are transcendental.
He is also known for the Kusmin-Landau inequality: If is continuously differentiable with monotonic derivative satisfying ( denotes the Nearest integer function) on a finite interval, then
