In this paper, we study rotation surfaces in the Minko-wski $3$-dimensional space with pointwise $1$-type Gauss map and obtain by the use of the concept of pointwise finite type Gauss map, a characterization theorem concerning rotation surfaces and constancy of the mean curvature of certain open subsets on these surfaces.
Keywords: Gauss map, Laplacian, pointwise $1$-type
