Abstract

Some aspects of the simple Lie algebra $\mathfrak{sl}(2,\mathbb{R})$ realized as a subalgebra of Noether point symmetries of Lagrangian systems and related inverse problems are discussed, specially in connection to Lagrangians of kinetic type and some geometric properties like sectional curvatures.
