Abstract

We classify finite-dimensional real nilpotent Lie algebras with 2-dimensional central commutator ideals admitting a Lie group of automorphisms isomorphic to SO2(). This is the first step to extend the class of nilpotent Lie algebras 𝔥 of type {n,2} to solvable Lie algebras in which 𝔥 has codimension one.
