Abstract
We consider T={z∈C:|z|=1},E⊂T ,mE > 0,G(E) is a certain subspace of L 1 (E) consisting of functions concentrated on E and integrable, and {dk}, (k ∈ ℤ) in a summable sequence of positive numbers. It is proved that if G(E)=Lp(E), p≥2, then there exists f∈G(E) such that |f(n)|≥dn, fˆ(n)|⩾dn,n∈Z (one of the questions involved in the majorization problem). Sufficient conditions are obtained for certain other function classes G(E). We study the question of partial majorization. Bibliography: 2 titles.
