We consider the space X of all analytic functionsf(s1 ,s2) = ∞∑aminexp(s1λm+s2μtn)of two complex variables s1 and s2, equipping it with the natural locally
Let n≥2. In this paper, the author establishes the L2(Rn)-boundedness of some oscillatory singular inte-grals with variable rough kernels by means of some esti
