A two-parameter Hedberg's method for fractional integration
Zipeng Wang
We introduce a 2-parameter Hedberg's method, and use it to prove a Hardy-Littlewood-Sobolev theorem for a new type of fractional integral operators, whose kernel has singularity on…

Regularity of Fourier integral operators on product spaces
Zipeng Wang
We study the regularity of Fourier integral operators, by allowing their symbols to satisfy certain multi-parameter characteristics. As a result, we give an extension of Seeger-Sog…
