The present Special Issue of Symmetry is devoted to two important areas of global Riemannian geometry, namely submanifold theory and the Geometry of Lie groups and Homogeneous spaces.
In th.
Lie\'s idea to use continuous symmetries in studying differential equations.
Klein\'s Erlangen Program and S.
Homogeneous Spaces are manifolds that admit a transitive Lie group action, historically related to F.
Submanifold theory originated from the classical Geometry of curves and surfaces.
