Some Inequalities for Polynomials
Let pn(z) be a polynomial of degree n. Given that pn(z) has a zero on the circle \z\ = p(0 < p < oo) we estimate maxi , Ä>1 |/>„(z)| in terms of maxi:i , |/>„(z)|. We also consider some other related problems. It is well known (see [8, p. 346], or [6, vol. 1, p. 137, Problem III 269]) that if pn(z) = 2yt=oaAz/c 's a polynomial of degree « such that |p„(z)| â M for |z| Si 1, then at a point z ou...
متن کاملSome compact generalization of inequalities for polynomials with prescribed zeros
Let $p(z)=z^s h(z)$ where $h(z)$ is a polynomial of degree at most $n-s$ having all its zeros in $|z|geq k$ or in $|z|leq k$. In this paper we obtain some new results about the dependence of $|p(Rz)|$ on $|p(rz)| $ for $r^2leq rRleq k^2$, $k^2 leq rRleq R^2$ and for $Rleq r leq k$. Our results refine and generalize certain well-known polynomial inequalities.
متن کاملSome Inequalities of Algebraic Polynomials
Erdös and Lorentz showed that by considering the special kind of the polynomials better bounds for the derivative are possible. Let us denote by Hn the set of all polynomials whose degree is n and whose zeros are real and lie inside [-1, 1 ). Let Pn € H„ and Pn ( 1 ) = 1 ; then the object of Theorem 1 is to obtain the best lower bound of the expression f}_{ \P¡,(x)\p dx for p > 1 and characteri...
متن کاملSome Inequalities on Chromatic Polynomials
For a given graph G, let P (G,λ) be the chromatic polynomial of G, where λ is considered to be a real number. In this paper, we study the bounds for P (G,λ)/P (G,λ − 1) and P (G,λ)/P (G − x, λ), where x is a vertex in G, λ ≥ n and n is the number of vertices of G.
