Abstract
Let X be a complex Banach space with and
be a standard operator algebra on X. Let k be a positive integer. For
, the k-commutator of A and B is defined by
with
. Let
be a map. We say that
is strong k-commutativity preserving if
for any
. In this paper, it is shown that, if the range of
contains all operators of rank one, then
is strong k-commutativity preserving if and only if there exist a functional
and a scalar
with
such that
for all
.
