A uniqueness theorem for the minimal surface equation
In 1991, \textit{P. Collin} and \textit{R. Krust} [Bull. Soc. Math. Fr. 119, 443-462 (1991; Zbl 0754.53013)] proved that if \(u\) satisfies the minimal surface equation in a strip with linear Dirichlet data on two sides, then \(u\) must be a helicoid. In this paper, we give a simpler proof of this result and generalize it.
