On the Gauss map of surfaces of revolution in a 3-dimensional Minkowski space
Let \(M\) be a spacelike or timelike surface of revolution in a three-dimensional Minkowski space. Let \(\xi\) denote the Gauss map of \(M\). The author classifies those surfaces whose Gauss map satisfies the condition \(\Delta \xi= A\xi\), where \(\Delta\) is the Laplacian of \(M\) and \(A\) is a fixed \(3\times 3\)-matrix.
