Abstract: A well-known theorem of Bernstein states that if a polynomial of degree of a complex variable has its modulus no larger than one on the unit disk then the modulus of its derivative will not exceed on the unit disk. Here we extend the theorem to polynomials on the unit ball in several complex variables.
