On an operator preserving polynomial inequalities

Nisar Ahmad Rather, Liyaqat Ali, Ishfaq Dar


In this paper, we consider an operator $N : \mathcal{P}_n\rightarrow \mathcal{P}_n$ on the space of polynomials $\mathcal{P}_n$ of degree at most $n$ and establish some compact generalizations of Bernstein-type polynomial inequalities, which include several well known polynomial inequalities as special cases.
