Pointwise Estimates of Multipliers

1997
Let T be a linear operator acting in a pair of r.i. spaces. An operator T 1 is said to be a transposed one with respect to T if for every measurable subsets e, f ⊂ [0,1]. A.P. Calderon proved the following theorem [52]. If T and its transposed operator T 1 have the weak types (1,1) and (2,2) with norms ≤ 1, then, for every t ∈ (0,1 ...

Pointwise multipliers of Lizorkin-Triebel spaces

1999
This paper contains two parts. In the first one we give a survey on sufficient and necessary conditions on a function f to belong to the set of all pointwise multipliers of certain Lizorkin-Triebel spaces. In part two we use these results to investigate under which geometrical conditions on the boundary the characteristic function XE of an open set E ...

Pointwise Multipliers on Musielak-Orlicz-Morrey Spaces

2017
In this paper we characterize pointwise multipliers from a Musielak-Orlicz-Morrey space to another Musielak-Orlicz-Morrey space. The set of all pointwise multipliers is also a Musielak-Orlicz-Morrey space.
