Abstract:

Let $d\alpha$ be a positive Borel measure in [-1,1] with $\alpha ’ > 0$ a.e. It is shown that the polynomials ${p_n}$ orthonormal with respect to this measure oscillate almost everywhere in [-1,1]. A function $F$ is also described that is a pointwise bound for ${p_n}$, exceeded only on sets of small measure. It is shown that $F$ is the best possible.
