Abstract:

We show in this short note an overdetermined problem for minimal surface equation, which is defined over a domain with connected boundary, has a solution if and only if the domain is either the complement of a round disk or a half plane. Equivalently, we show that a minimal graph with connected zero boundary and makes a constant angle at all boundary points with a plane is a part of a catenoid or a half-plane.
