Moduli space theory for constant mean curvature surfaces immersed in space-forms. (English) Zbl 1136.53048

The authors study surfaces with constant mean curvature \(c\) in a \(3\)-dimensional real space form of constant sectional curvature \(k\). They are particularly interested in the case when \(k +c^2\) is strictly negative. The authors want to determine solutions of the Gauss and Codazzi equation for a fixed Riemannian surface. In order to do so, they take a fixed Riemann surface with initial constant curvature metric \(g\) (the actually induced metric on the constant mean curvature surface will be conformally equivalent to \(g\)) and a holomorphic quadratic differential, which is transformed into a \((-1,1)\) form using the metric. The main result states that, given a Riemann surface and a \((-1,1)\) cohomology class, if \(k +c^2\) is negative, there exists a unique solution of the Gauss-Codazzi equations.
