Generalizations of Bernstein and Turán-type inequalities for the polar derivative of a complex polynomial

A Mir - Mediterranean Journal of Mathematics, 2020 - Springer
The goal of this paper is to extend to the polar derivatives some previous inequalities
between the L^ γ L γ-norms of the derivative and of the polynomial itself, in case when the …

Bernstein and Turán-type inequalities for a polynomial with constraints on its zeros

A Mir, D Breaz - Revista de la Real Academia de Ciencias Exactas …, 2021 - Springer
This paper considers the well known Bernstein and Turán-type inequalities that relate the
uniform norm of a polynomial to that of its derivative on the unit circle in the plane. Here, we …
