      He liked to see what happened when the polynomials are restricted in certain ways. Markov- and Bernstein-type inequalities for classes of polynomials under various constraints have attracted a number of authors. In a short paper in 1940 Erd˝os [E40] has found a class of restricted polynomials for which the Markov factor n2 improves to cn.

      Local Lp inequalities for Gegenbauer polynomials Laura De Carli Abstract In this paper we prove new Lp estimates for Gegenbauer polynomials P(s) n (x). We let dµ s(x) = (1 − x2)s− 1 2 dxbe the measure in (−1,1) which makes the polynomials P (s) n (x) orthogonal, and we compare the Lp(dµ s) norm of P (s) n (x) with that of xn.We also prove new Lp(dµ s) estimates of the restriction of ...

      Markov- and Bernstein-type inequalities for classes of polynomials under various constraints have attracted a number of authors. For example, it has been observed by Bernstein [B58] that Markov’s inequality for monotone polynomials is not essentially better than for arbitrary polynomials. He proved that if n is odd, then

For a survey of such inequalities, we refer the reader to [4].

      We will need these inequalities in Section 6 to give upper bounds for the distance of the consecutive zeros of orthogonal polynomials. Since for q >O the qth power of a generalized polynomial is also a generalized polynomial, we can easily derive L, + L,(w) inequalities from our L, --f L,(w) inequalities.

      Solving Polynomial Inequalities Note: This material is to supplement Section 3.6. Unlike linear inequalities, polynomial inequalities cannot always be solved with just algebra, and other techniques will need to be used. We will learn to solve inequalities once they are of the form where one side of the inequality is a polynomial and the other is 0.

In [4], in connection with his analysis of the convergence of Newton’s method for calculating the zeros of polynomials, Smale established inequalities for critical values and asked about the sharpness of these estimates ([4], pp. 9, 11, 31–33). In particular, for polynomials
