The structure of the Lie algebras with almost dimensionally nilpotent inner
derivations is studied. It is proved that, if the base held is of characte
ristic 0, then, when d > 6 is odd, there exist just two d-dimensional Lie a
lgebras; when d > 6 is even, there exists just one d-dimensional Lie algebr
a such that these Lie algebras are nonsolvable and have some almost dimensi
onally nilpotent inner derivations. (C) 2000 Elsevier Science Inc. All righ
