	  abstract     = {A Banach space operator T obeys property (gm) if the
isolated points of the spectrum σ(T) of T which are eigenvalues
are exactly those points λ of the spectrum for which T − λI is
a left Drazin invertible. In this article, we study the stability of
property (gm), for a bounded operator acting on a Banach space,
under perturbation by finite rank operators, by nilpotent operators,
by quasi-nilpotent operators, or more generally by algebraic operators
commuting with T.},
