be any of the following properties: the weak
ideal property, the topological dimension zero,
the combination of pure infiniteness and the
ideal property, residual (SP), pure
infiniteness, strong pure infiniteness, provided that the zero C*-algebra
is included, and
-stability for a separable unital strongly self-absorbing
be a separable unital C*-algebra with unit
and assume that there exist non-zero projections
We show that
(in fact, we prove a much more general
result). We also show that, somehow surprisingly, for two large classes
of non-zero C*-algebras, if
then the fact that
has the weak ideal property
implies (or, is equivalent to) the fact that
have the weak ideal property. We prove
that one of these two results still holds if we replace the
weak ideal property by some related properties.
Key Words: Weak ideal property, topological
