We show that the extension property for pure states of a C\*-subalgebra B of a C\*-algebra A leads to the existence of a projection of norm one R: A Γ„ B in the case where B is liminal with Hausdorff primitive ideal space. Furthermore, R is given by a ``Dixmier process'' in which the averaging is eff

It is shown that the conventional linearization scheme, used to reduce the dimensional@ of many-fermion-nucleon operators (e.g. in deriving RPA equations), is inadequate for the neutronrich nuclei, i.e., it is non-isoinvariant. A similar but isoinvariant scheme is introduced and applied successfully
