Fractional type Marcinkiewicz integral operators associated to surfaces
In this paper, we discuss the boundedness of the fractional type
Marcinkiewicz integral operators associated to surfaces, and extend a result
given by Chen, Fan and Ying in 2002. They showed that under certain conditions
the fractional type Marcinkiewicz integral operators are bounded from the
Triebel-Lizorkin spaces to . Recently the second author, together with Xue and Yan, greatly weakened
their assumptions. In this paper, we extend their results to the case where the
operators are associated to the surfaces of the form .
To prove our result, we discuss a characterization of the homogeneous
Triebel-Lizorkin spaces in terms of lacunary sequences.Comment: 27page
Triebel--Lizorkin space estimates for multilinear operators of sublinear operators
In this paper, we obtain the continuity for some multilinear operators
related to certain non-convolution operators on the Triebel--Lizorkin space.
The operators include Littlewood--Paley operator and Marcinkiewicz operator.Comment: 15 pages, no figures, no table
Boundedness of rough integral operators on Triebel-Lizorkin spaces
We prove the boundedness of several classes of rough integral operators on Triebel-Lizorkin spaces. Our results represent improvements as well as natural extensions of many previously known results
A Note on a Class of Generalized Parabolic Marcinkiewicz Integrals along Surfaces of Revolution
In this article, certain sharp Lp estimates for a specific class of generalized Marcinkiewicz
operators with mixed homogeneity associated to surfaces of revolution are established. By virtue of
Yano’s extrapolation argument, beside these estimates, the Lp boundedness of the aforementioned
operators under weaker assumptions on the kernels is confirmed. The obtained results in this article
are fundamental extensions and improvements of numerous previously known results on parabolic
generalized Marcinkiewicz integrals
