Abstract
In this paper, it is proved that the Banach algebra A(ℒ)macr;, generated by a Lie algebra ℒ of operators, consists of quasinilpotent operators if ℒ consists of quasinilpotent operators and A(ℒ)̄ consists of polynomially compact operators. It is also proved that A(ℒ)̄ consists of quasinilpotent operators if ℒ is an essentially nilpotent Engel Lie algebra generated by quasinilpotent operators. Finally, Banach algebras generated by essentially nilpotent Lie algebras are shown to be compactly quasinilpotent.
