to -boundedness of fractional integral operators having a flag kernel
Jiashu Zhang, Zipeng Wang
We study a family of fractional integral operators whose kernels satisfying an non-isotropic dilation have singularity on a coordinate subspace. A characterization is given for the…

A multi-parameter family of Fourier integral operators
Mengmeng Dou, Zipeng Wang, Jiashu Zhang
We study a new class of Fourier integral operators defined in R^N. Their symbols are allowed to satisfy a differential inequality with certain multi-parameter characteristic. We pr…
