Abstract

For third-order ordinary differential equations admitting a Lie symmetry algebra isomorphic to \(\mathfrak {so}(3,\mathbb {C})\) it is proved the existence of a solvable structure constructed out of the symmetry generators of the algebra. This solvable structure is explicitly obtained in terms of solutions to a second-order linear ordinary differential equation. Once the solvable structure is known, a complete set of first integrals can be computed by quadratures. Moreover, it is proved that the general solution can be obtained in parametric form and expressed in terms of solutions to a second-order linear equation.
