摘要
We state and discuss several interrelated results, conjectures, and questions regarding contractive inequalities for classical H-p spaces of the unit disc. We study both coefficient estimates in terms of weighted l(2) sums and the Riesz projection viewed as a map from L-q to H-p with q >= p. Some numerical evidence is given that supports our conjectures.
