Weighted composition operators on weighted Lorentz spaces

Similarity:

The boundedness, compactness and closedness of the range of weighted composition operators acting on weighted Lorentz spaces L(p,q,wdμ) for 1 < p ≤ ∞, 1 ≤ q ≤ ∞ are characterized.

A new approach to nonlinear singular integral operators depending on three parameters

Gumrah Uysal (2016)

Open Mathematics

Similarity:

In this paper, we present some theorems on weighted approximation by two dimensional nonlinear singular integral operators in the following form: T λ ( f ; x , y ) = ∬ R 2 ( t − x , s − y , f ( t , s ) ) d s d t , ( x , y ) ∈ R 2 , λ ∈ Λ , T λ ( f ; x , y ) = 2 ( t - x , s - y , f ( t , s ) ) d s d t , ( x , y ) 2 , λ Λ , where Λ is a set of non-negative numbers with accumulation point λ0.
