RT Journal Article T1 Solvable Lie algebras with naturally graded nilradicals and their invariants A1 Ancochea Bermúdez, José María A1 Campoamor-Stursberg, Rutwig A1 Vergnolle, L.G. AB The indecomposable solvable Lie algebras with graded nilradical of maximal nilindex and a Heisenberg subalgebra of codimension one are analysed, and their generalized Casimir invariants are calculated. It is shown that rank one solvable algebras have a contact form, which implies the existence of an associated dynamical system. Moreover, due to the structure of the quadratic Casimir operator of the nilradical, these algebras contain a maximal non-abelian quasi-classical Lie algebra of dimension 2n - 1, indicating that gauge theories (with ghosts) are possible on these subalgebras.
