摘要
The oscillatory singular integrals we will consider are T(f)(x)=∫<sub>R</sub><sup>n</sup>e<sup>iπp(x,y)</sup>k(x-y)f(y)dy, (1) where k(x) is a Calderon-Zygmund standard kernel, i. e. k(x)=Ω(x)/|x|<sup>n</sup>, where Ω(x) is a homogeneous function and has enough smoothness on the unit sphere of R<sup>n</sup>, and p(x, y) is an arbitrary real-valued polynomial. The purpose of this note is to prove the following theorem.
