Add to ORKGAbstract. We obtain an exhaustive classification of totally umbilical surfaces in unimodular and non-unimodular simply-connected 3-dimen-sional Lie groups endowed with arbitrary left-invariant Riemannian met-rics. This completes the classification of totally umbilical surfaces in homogeneous Riemannian 3-manifolds. 1
