Almost inner derivations of 2-step nilpotent Lie algebras of genus 2
Dietrich Burde, Karel Dekimpe, Bert Verbeke
We study almost inner derivations of -step nilpotent Lie algebras of genus , i.e., having a -dimensional commutator ideal, using matrix pencils. In particular we determine…

Almost inner derivations of Lie algebras II
Dietrich Burde, Karel Dekimpe, Bert Verbeke
We continue the algebraic study of almost inner derivations of Lie algebras over a field of characteristic zero and determine these derivations for free nilpotent Lie algebras, for…

Almost inner derivations of Lie algebras
Dietrich Burde, Karel Dekimpe, Bert Verbeke
We study almost inner derivations of Lie algebras, which were introduced by Gordon and Wilson in their work on isospectral deformations of compact solvmanifolds. We compute all alm…
