Abstract: In this paper, the weak (1,1) boundedness of oscillatory singular integral with variable phase P(x)γ(y) for any x, y ∈ ℝ, $$Tf(x)\;:=\;{\rm{p}}.\>{\rm{v}}.\>\int_{- \infty}^\infty {{{\rm{e}}^{{\rm{i}}P(x)\gamma (y)}}f(x\;-\;y)\frac{dy}{y}}$$ is studied, where P is a real monic polynomial on… read more here.
