Query: Compactness of Hankel operators with continuous symbols   Let $\Omega$ be a bounded convex Reinhardt domain in $\mathbb{C}^2$ and
$\phi\in C(\bar{\Omega})$. We show that the Hankel operator $H_{\phi}$ is
compact if and only if $\phi$ is holomorphic along every non-trivial analytic
disc in the boundary of $\Omega$.
