On the boundedness of a family of oscillatory singular integrals
Let $\Omega \in H^1(\mathbb{S}^{n-1})$ with mean value zero, $P$ and $Q$ be polynomials in $n$ variables with real coefficients and $Q(0)=0$. We prove that \[ \Biggl |\mbox {p.v.}\int _{\mathbb{R}^n}e^{i(P(x)+1/Q(x))}\frac{\Omega (x/|x|)}{|x|^n}\mathrm{d}x\Biggr | \le A \Vert \Omega \Vert _{H^1(\mat...
