TITLE The L^p-L^q estimates for degenerate Radon transforms in C^2
ABSTRACT

We obtain some $L^p \ra L^q$ estimates for the semi-translation invariant Radon transform defined by
\bgn{equation*}
Rf(z,\tau)=\int_\mathbb{C}f(\xi,\tau+P(z,\xi))\psi(z,\xi)dA_{\xi},
\end{equation*}
where $\psi$ is a cutoff function supported in a small neighborhood of the origin. Here, $dA_{\xi}=dxdy$ provided that $\xi=x+iy$, where $x,y\in\mathbb{R}$.
