本文利用小波变换给出了L2(En+1+,(dxdy)/(yn+1)中的柱面函数空间的一种正交直和分解.在这种分解下定义了Toeplitz-Hankel型算子,得到了类似的Schatten-Von Neumann性质. 相似文献

We study the structure of Bernstein's first summable operators and show that they con-verge uniformly to continuons functions on the special real orthogonal group SO(n)in thispaper.In addition,we have also discussed the approximation degree to a class of functionLipα(0<α≤1)on SO(n). 相似文献

The aim of this paper is to prove a new version of the Riesz-Thorin interpolation theorem on LP(C,H).In the sense of Cullen-regular,we show Hadamard’s three-lines theorem by means of the Maximum modulus principle on a symmetric slice domain.In addition,two applications of the Riesz-Thorin theorem are presented.Finally,we investigate two kinds of Calderón’s complex interpolation methods in LP(C,H). 相似文献

Let D be the unit disk in the complex plane with the weighted measure dμβ(z) = (β+1)--π(1-|z|2)βdm(z)(β>-1). Then L2(D,dμβ(z)) = ∞k=0(Aβk Aβk) is the orthogonal direct sum decomposition.In this paper, we define the Hankel and Toeplitz type operators, and study the boundedness, compactness and Sp-criteria for them. 相似文献

令P=NAM是SU(n+1,1)的极小抛物子群,它可以看作是Heisenberg群Hn上的仿射自同构群.根据[1]中的可允许条件,我们给出了Hn上的带状小波.利用小波变换,我们得到了L2(Un+1,dμl(z,t,ρ))的另一个正交直和分解.进一步还给出了L2(P,dμl(z,t,ρ,u))的正交分解. 相似文献
