RT Journal Article T1 On the invariants of some solvable rigid Lie algebras A1 Campoamor Stursberg, Otto-Rudwig AB We determine fundamental systems of invariants for complex solvable rigid Lie algebras having nonsplit nilradicals of characteristic sequence (3, 1, .., 1), these algebras being the natural followers of solvable algebras having Heisenberg nilradicals. A special case of this allows us to obtain a criterion to determine the number of functionally independent invariants of rank one subalgebras of (real or complex) solvable Lie algebras. Finally, we give examples of the inverse procedure, obtaining fundamental systemsof an algebra starting from rank one subalgebras PB American Institute of Physics SN 0022-2488 YR 2003 FD 2003 LK https://hdl.handle.net/20.500.14352/50723 UL https://hdl.handle.net/20.500.14352/50723 LA eng DS Docta Complutense RD 24 abr 2025
