Rotational Ricci surfaces

Abstract

We classify rotational surfaces in the three-dimensional Euclidean space whose Gaussian curvature KK satisfies \begin{equation*} K\Delta K - \|\nabla K\|^2-4K^3 = 0. \end{equation*} These surfaces are referred to as rotational Ricci surfaces. As an application, we show that there is a one-parameter family of such surfaces meeting the boundary of the unit Euclidean three-ball orthogonally. In addition, we show that this family interpolates a vertical geodesic and the critical catenoid.

Term "free boundary" in Section 4 changed for "meeting the boundary orthogonally". Final version to appear in Ann. Mat. Pura Appl
