Abstract

Suppose that MM is a Riemann surface with boundary M\partial M, Λ\Lambda is its DN-map, and E:MCn\mathscr E:M\to\mathbb{C}^{n} % JM\mathfrak{J}_{M} is a holomorphic immersion. Let MM' be diffeomorphic to MM, M=M\partial M=\partial M'; let Λ\Lambda' be the DN map of MM'. Let us write MMtM'\in\mathbb M_t if ΛΛH1(M)L2(M)t\parallel\Lambda'-\Lambda\parallel_{H^{1}(\partial M)\to L_{2}(\partial M)}\leqslant t holds. We show that, for any holomorphic immersion E:MCn\mathscr{E}: M \to \mathbb C^n (n1n\geqslant 1), the relation \begin{equation*} \sup_{M'\in \mathbb{M}_{t}}\inf_{\mathscr{E}'}d_{H}(\mathscr E'(M'),\mathscr{E}(M))\underset{t\to 0}{\longrightarrow}0, \end{equation*} holds, where dHd_H is the Haussdorf distance in Cn\mathbb C^n and the infimum is taken over all holomorphic immersions E:MCn\mathscr E': M'\mapsto\mathbb C^n.
