Abstract: Under some restrictions on critical values of an algebraic polynomial with complex coefficients, a sharp inequality for the product of certain powers of moduli of its derivatives at its zeros is established. The equality is attained for the suitable Chebyshev polynomial of the first kind.
Key words and phrases: polynomial, Chebyshov polynomial, critial values, symmetrization.
