Markov type estimates for derivatives of polynomials of special type
The main purpose of this paper is to give a common generalization of Videnskij's and Szabados' result for trigonometric polynomials. A very essential tool to prove Markov type estimates for derivatives of trigonometric polynomials is defined and 5 theorems are given. From Theorem 1 the Markov type estimates for algebraic polynomials of special type is obtained.
