Abstract:

In this paper we give Markov Bernstein type inequalities for derivative of polynomials on some subsets of R. We define two different kinds of functions measuring the density of the sets considered, and in most cases we establish sharp inequalities for the Markov—Bernstein factor at the accumulation point of the set.
