The Gauss map of minimal graphs in the Heisenberg group. (English) Zbl 1268.22006

The geometry of surfaces of the Heisenberg group \(H_3\) endowed with a fixed left-invariant Riemannian metric is studied. The Gauss map for hypersurfaces of any Lie group is defined and the classification of minimal surfaces in \(H_3\) with Gauss maps of ranks zero and one is given. There is a reference list of 17 items.
