Bilinear generalized Radon transforms in the plane

Allan Greenleaf, Alex Iosevich, Ben Krause +1

Let $\sigma$ be arc-length measure on $S^1\subset {\mathbb{R}}^2$ and $\Theta$ denote rotation by an angle $\theta \in (0,\pi ]$. Define a model bilinear generalized Radon transform, $$B_θ(f,g)(x)=\int…
