Minimal submanifolds in \(\mathrm{Sol}_0^4\) (Q6174362)

The authors study several minimal submanifolds in the 4-dimensional homogeneous solvable Lie group Sol\(_0^4\) equipped with the standard globally conformal Kähler structure. They begin with the classification of minimal proper invariant submanifolds in Sol\(_0^4\) and show that those which are tangent or normal to the Lee field are cylindrical surfaces. The also find minimal CR-products in Sol\(_0^4\).
