    Let \(\Omega\) be an open subset of \(\mathbb C^N\), with \(\partial\Omega\in{\mathcal C}^2\). A continuous function \(f\) on \(\partial\Omega\) which is the restriction of a holomorphic function \(\widetilde{f}\) in \(\Omega\) satisfies \[ \int_{\partial D}{f\omega}=0 \tag{*} \] for all analytic discs \(D\) with \({\partial D}\subset\partial\Omega\) and every holomorphic one form in \(D\). Morera's condition (\(*\)) for all \(\omega\) with constant coefficients and \(D\) contained in a complex line and close to the intersection \(D_0\) of \(\partial\Omega\) with a complex line \(L_0\) is sufficient for the holomorphic extension of \(f\) to a neighborhood of \(D_0\) in \(\Omega\) when \(\Omega\) is convex. When \(\Omega\) is assumed to be strictly pseudoconvex, the authors show that the same conclusion holds under the stronger assumption that (\(*\)) is valid for all \(\omega\) whose coefficients are first degree polynomials and all transversally embedded analytic discs \(D\) in a neighborhood of a transversally embedded analytic disc \(D_0\).
