On boundary regularity of proper holomorphic mappings (Q1433427)

This paper shows that a proper holomorphic mapping \(f: D\longrightarrow D^{\prime}\) from a domain \(D\subset {\mathbb C}^n\) with real-analytic boundary to a domain \(D^{\prime}\subset{\mathbb C}^n\) with real-algebraic boundary extends holomorphically to a neighborhood of \(\overline{D}.\)
