摘要：

Fourier transform norm inequalities, ∥ f ̂∥q,μ <- C ∥f∥p,υ, are proved for measure weights μ on moment subspaces of Lpυ(Rn). Density theorems are established to extend the inequalities to all of Lpυ(Rn). In both cases the conditions for validity are computable. For n ≥ 2, μ and υ are radial, and the results are applied to prove spherical restriction theorems which include power weights υ(t) = = ∥t∥α, n (p′ - 1) < α < (p′ + n) (p′ - 1). © 1992.
