Abstract
Let \(\Omega \) be a \(C^2\)-smooth bounded pseudoconvex domain in \(\mathbb {C}^n\) for \(n\ge 2\) and let \(\varphi \) be a holomorphic function on \(\Omega \) that is \(C^2\)-smooth on the closure of \(\Omega \). We prove that if \(H_{\overline{\varphi }}\) is in Schatten p-class for \(p\le 2n\) then \(\varphi \) is a constant function. As a corollary, we show that the \(\overline{\partial }\)-Neumann operator on \(\Omega \) is not Hilbert–Schmidt.
