Abstract:
We prove ${L^2}$ boundedness of the oscillatory singular integral \[ Tf(x,y) = \iint \limits _{{D_y}} {\frac {{\operatorname {exp} (2\pi iN(y)x’)}}{{x’y’}}}f(x - x’,y - y’)dx’dy’\] where $N(y)$ is an arbitrary integer-valued ${L^\infty }$ function and where nothing is assumed on the dependency upon $y$ of the domain of integration ${D_y}$. We also prove ${L^2}$ boundedness of the corresponding maximal opertaor. Operators of this kind appear in a problem of a.e. convergence of double Fourier series.References
