Özet : Let $\Omega$ be a bounded convex domain in $\mathbb{C}^2$ with $C^1$-smooth boundary and $\varphi\in C^1(\Omega)$ such that $\varphi$ is harmonic on the analytic discs in the boundary. We estimate the essential norm of the Hankel operator $H_\varphi$ in terms of the $\overline{\partial}$ derivatives of $\varphi$ ''along'' the discs in the boundary. This is joint work with Zeljko Cuckovic.
