چکیده
Recall that the Lorentz ideal C− p is the collection of operators A satisfying the condition ‖A‖p = ∑∞ j=1 j sj(A) < ∞. Consider Hankel operators Hf : H(S) → L(S, dσ) H(S), where H(S) is the Hardy space on the unit sphere S in C. In this paper we characterize the membership Hf ∈ C− p , 2n < p <∞.

Hankel Operators on Weighted Bergman Spaces and Norm Ideals
Consider Hankel operators Hf on the weighted Bergman space L 2 a(B, dvα). In this paper we characterize the membership of (H∗ fHf ) s/2 = |Hf | in the norm ideal CΦ, where 0 < s ≤ 1 and the symmetric gauge function Φ is allowed to be arbitrary.
متن کاملA Local Inequality for Hankel Operators on the Sphere and Its Application
Let H(S) be the Hardy space on the unit sphere S in C. We establish a local inequality for Hankel operators Hf = (1 − P )Mf |H(S). As an application of this local inequality, we characterize the membership of Hf in the Lorentz-like ideal C p , 2n < p <∞.
متن کاملComposition operators acting on weighted Hilbert spaces of analytic functions
In this paper, we considered composition operators on weighted Hilbert spaces of analytic functions and observed that a formula for the essential norm, gives a Hilbert-Schmidt characterization and characterizes the membership in Schatten-class for these operators. Also, closed range composition operators are investigated.
متن کاملSchatten Class Membership of Hankel Operators on the Unit Sphere
Let H(S) be the Hardy space on the unit sphere S in C, n ≥ 2. Consider the Hankel operator Hf = (1 − P )Mf |H(S), where the symbol function f is allowed to be arbitrary in L(S, dσ). We show that for p > 2n, Hf is in the Schatten class Cp if and only if f − Pf belongs to the Besov space Bp. To be more precise, the “if” part of this statement is easy. The main result of the paper is the “only if ...

A $it{weighted~slant~Toep}$-$it{Hank}$ operator $L_{phi}^{beta}$ with symbol $phiin L^{infty}(beta)$ is an operator on $L^2(beta)$ whose representing matrix consists of all even (odd) columns from a weighted slant Hankel (slant weighted Toeplitz) matrix, $beta={beta_n}_{nin mathbb{Z}}$ be a sequence of positive numbers with $beta_0=1$. A matrix characterization for an operator to be $it{weighte...
