Bilinear singular integral operators with kernels in weighted spaces
Bilinear singular integral operators with kernels in weighted spaces
We study boundedness properties of one-dimensional bilinear singular integral operators with homogeneous kernels whose restriction $\Omega$ to the unit sphere $\mathbb S^1$ has vanishing integral and belongs to $L^q(\mathbb S^1)$ for some $q>1$. Under the additional assumption that $\Omega$ is supported away from certain degenerate points, we establish the full …
