Hardy-Type Operators

2002
In [118] Hardy proved the following celebrated inequality: let 1 < p < ∞ and set F(x) = ∫ o x f (t)dt, where f is a non-negative measurable function on (0, ∞). Then, if e < 1/p′ = 1–1/p, $$ \int_0^\infty {{F^p}} (x){x^{p(\varepsilon - 1)}}dx \leqslant C\int_0^\infty {{f^p}} (x){x^{\varepsilon p}}dx $$ (2.1.1) for some constant C > 0 ...

Hankel and Toeplitz operators in hardy spaces

Journal of Soviet Mathematics, 1987
Some spaces of analytic functions are introduced and some theorems concerning the theory of Toeplitz and Hankel operators on these spaces are investigated. The main result is theorem 4, where the symbols of Toeplitz and Hankel operators from \(H^ p\) to \(H^ q ...

Hardy–Orlicz Spaces and Their Multiplication Operators

Acta Mathematica Sinica, English Series, 2005
The author investigates the relation between Hardy and Hardy--Orlicz spaces. Also, multiplication operators on Hardy--Orlicz spaces are discussed and the commutant of the multiplication operators \(M_z\) and the spectrum and essential spectrum of a multiplication operator on Hardy--Orlicz spaces are characterized.

On Hardy–Steklov and geometric Steklov operators

Mathematische Nachrichten, 2007
AbstractA new (non‐Muckenhoupt type) weight characterization for the boundedness of the general Hardy–Steklov operator is obtained in the case 1 < p ≤ q < ∞. The estimates obtained for the norm of the Hardy–Steklov operator allow the limiting procedure and as a result the boundedness of the corresponding geometric Steklov operator is investigated.
