Marcinkiewicz Interpolation Theorem for Spaces of Hardy Type
網頁(bonus) We state here two theorems to illustrate the erratic behaviors of polynomial interpolation, see [Kre12, Chapter 8] for proofs. Theorem 2.7.1 (Marcinkiewicz) . For each function f ∈ C ([ a, b ]) , there exists a sequence of sets of nodes x n j , j = 0 , . . . , n n ∈ N such that the Lagrange interpolant p n ∈ P n of f at nodes x n j , 0 ≤ j ≤ n , converges to f … 網頁而条件 (1)可以放宽到: T (s) 总是把简单函数映到局部可积的函数,因它在证明中的唯一作用就是确保积分总是存在。.

Stein's theorem on the interpolation of a family of operators between two analytic spaces is generalized, both to a multiply connected domain and to an interpolation between more than two spaces. The theorem is then applied to get setwise upper bounds for spectra of convolution operators on Lp of the circle. how can i retire in canada
