Recent progress of Littlewood-paley Theory with chirp function
Xiang Li Qianjun He, Zunwei Fu
Littlewood--Paley theory is a fundamental tool for frequency localization, square-function control, and multiplier analysis, yet a systematic counterpart in the fractional Fourier…
Sharp constants for a class of linear integral operators on higher-dimensional product spaces
Xiang Li, Zunwei Fu, Zhongci Hang
In this paper, we will study a class of linear integral operators with the nonnegative kernels on higher-dimensional product spaces, the norms of the operators can be obtained by i…
Fractional Fourier transforms on and applications
Wei Chen, Zunwei Fu, Loukas Grafakos +1
This paper is devoted to the theory of the fractional Fourier transform (FRFT) for . In view of the special structure of the FRFT, we study FRFT proper…
Commutators of maximal functions on spaces of homogeneous type and their weighted, local versions
Zunwei Fu, Elodie Pozzi, Qingyan Wu
We establish the characterizations of commutators of several versions of maximal functions on spaces of homogeneous type. In addition, with the aid of interpolation theory, we prov…
Morrey meets Muckenhoupt: A note on Nakai's generalized Morrey spaces and applications
Xian Ming Hou, Qingyan Wu, Zunwei Fu +1
The goal of this paper is to extend Nakai's generalized Morrey spaces to a wider function class, the one-sided Muckenhoupt weighted case. Morrey matching Muckenhoupt enables us to…
Boundedness of sublinear operators on weighted Morrey spaces and applications
Zunwei Fu, Shanzhen Lu, Shaoguang Shi
We study the boundedness of some sublinear operators on weighted Morrey spaces under certain size conditions. These conditions are satisfied by most of the operators in harmonic an…
