Abstract

Purpose

The purpose of this paper is to study the multilinear commutator in weighted Morrey space.

Methods

We divide the multilinear commutator into four parts and apply with the methods of weighted Lebesgue space and Pérez and Trujillo-González.

Results

Let <a onClick="popup('http://www.iaumath.com/content/6/1/33/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.iaumath.com/content/6/1/33/mathml/M1">View MathML</a>; we show that <a onClick="popup('http://www.iaumath.com/content/6/1/33/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.iaumath.com/content/6/1/33/mathml/M2">View MathML</a> is bounded on weighted Morrey spaces Lp,κ(w),1 < p < ,0 < κ < 1,w ∈ Ap. When p = 1, it is shown that <a onClick="popup('http://www.iaumath.com/content/6/1/33/mathml/M3','MathML',630,470);return false;" target="_blank" href="http://www.iaumath.com/content/6/1/33/mathml/M3">View MathML</a> is weak type bounded on weighted Morrey space.

Conclusions

We extend the results of the commutator in weighted Morrey space. In particular, for m=1, this result is also new in the classical commutator.
