An elementary proof of the Ohsawa-Takegoshi extension theorem
The paper contains a different proof of the famous Ohsawa-Takegoshi theorem on the extension of a holomorphic function defined on an intersection of a hyperplane and a bounded pseudoconvex domain to the whole domain with the control of a weighted \(L^2\) norm of the function. The proof is based on a variant of Hörmander's \(L^2\) estimates for the \(\overline{\partial}\) operator.
