On bilinear Hilbert transform along two polynomials

Abstract

We prove that the bilinear Hilbert transform along two polynomials $B_{P,Q}(f,g)(x)={\int }_{\mathbb{R}}f(x-P(t))g(x-Q(t))\frac{dt}{t}$ is bounded from $L^p\times L^q$ to $L^r$ for a large range of $(p,q,r)$, as long as the polynomials $P$ and $Q$ have distinct leading and trailing degrees. The same boundedness property holds for the corresponding bilinear maximal function ${\mathcal{M}}_{P,Q}(f,g)(x)={\sup }_{\epsilon >0}\frac{1}{2\epsilon }{\int }_{-\epsilon }^{\epsilon }|f(x-P(t))g(x-Q(t))|dt$.
