E.V. Petrov The Gauss Map of Submanifolds in the Heisenberg Group // Differential Geometry and its Applications, 2011, vol. 29, p. 516–532, 2011

We obtain criteria for the harmonicity of the Gauss map of submanifolds in the Heisenberg group and consider the examples demonstrating the connection between the harmonicity of this map and the properties of the mean curvature field. Also, we introduce a natural class of cylindrical submanifolds and prove that a constant mean curvature hypersurface with harmonic Gauss map is cylindrical.

Keywords: Heisenberg group, Gauss map, harmonic map, mean curvature field, constant mean curvature hypersurface

Ye.V. Petrov Submanifolds with the Harmonic Gauss Map in Lie Groups // Journ. of Math. Phys., An., Geom., 4 (2008), no. 2, p. 278-293, 2008

In this paper we find a criterion for the Gauss map of an immersed smooth submanifold in some Lie group with left invariant metric to be harmonic. Using the obtained expression we prove some necessary and sufficient conditions for the harmonicity of this map in the case of totally geodesic submanifolds in Lie groups admitting biinvariant metrics. We show that, depending on the structure of the tangent space of a submanifold, the Gauss map can be harmonic in all biinvariant metrics or non-harmonic in some metric. For $2$-step nilpotent groups we prove that the Gauss map of a geodesic is harmonic if and only if is constant.

Keywords: Left invariant metric, biinvariant metric, Gauss map, harmonic map, $2$-step nilpotent group, totally geodesic submanifold

Ye.V. Petrov The Gauss Map of Hypersurfaces in 2-Step Nilpotent Lie Groups // Journ. of Math. Phys., An., Geom., 2 (2006), no. 2, p. 186-206, 2006

In this paper we consider smooth oriented hypersurfaces in $2$-step nilpotent Lie groups with a left invariant metric and derive an expression for the Laplacian of the Gauss map for such hypersurfaces in the general case and in some particular cases. In the case of CMC-hypersurface in the $2m+1$-dimensional Heisenberg group we also derive necessary and sufficient conditions for the Gauss map to be harmonic and prove that for $m=1$ all CMC-surfaces with the harmonic Gauss map are ''cylinders''.
