Estimates of the growth of orthogonal polynomials whose weight is bounded away from zero
E. A. Rakhmanov
Abstract:
It is proved that for any $\varepsilon>0$ and any point $x_0$ in the interval $(-1,1)$ there exists a weight function $\rho(x)$ on $[-1,1]$ with $\rho(x)\geqslant1$, $x\in[-1,1]$, such that the following inequalities hold for the corresponding orthonormal polynomials $p_n(x)$:
$$
|p_n(x_0)|\geqslant n^{1/2-\varepsilon},\qquad n\in\Lambda,
$$
where $\Lambda$ is some infinite sequence of positive integers.
