As a consequence, it is proved that any quasinilpotent Lie algebra of compact operators on a Banach space is triangularizable. We extend the Berger&#150;Wang formula to precompact sets of essentially scalar operators and prove the continuity of the joint spectral radius on them.<B> Copyright 2000 Academic Press.</B></P>",
