Regularity of Fourier integrals on product spaces
Chaoqiang Tan, Zipeng Wang
We study a family of Fourier integral operators by allowing their symbols to satisfy a multi-parameter differential inequality on R^N. We show that these operators of order -(N-1)/…

Boundedness of New Type Fourier Integral Operators with Product Structure
Chaoqiang Tan, Zipeng Wang
We investigate a class of Fourier integral operators with weakened symbols, which satisfy a multi-parameter differential inequality in . We establish that these operators ret…
